This post is very triggering for XCOM players


NachoBacon4U269

95% to hit is a miss 95% of the time but 80 % to hit is a hit 50% of the time unless it’s your favorite guy getting shot


Tarc_Axiiom

IT'S JUST NOT MATHEMATICALLY POSSIBLE! ^It ^is! SHIT THE FUCK UP!


Stargate525

Will you roll under a 5 more times if you roll 500 times, or 5? You miss more 90%+ shots because that's *all you take*. 


NegaDoug

I had a buddy who often used the phrase, "What were the odds of THAT happening?" After I picked up on his trend, I would annoy him by saying, "Well, it happened, so apparently 100%." "Dammit that's not how statistics works!" He was right, of course, but I always led him to believe that I thought I was right.


Tarc_Axiiom

>"Well, it happened, so apparently 100%." These are actually fighting words in the XCOM community.


OrangeGills

XCOM is the source of my (very harmful) risk aversion, and also the source of my (somewhat useful) habit in ensuring redundancy when there is risk.


SonoPelato

Looooool


jwr410

75. That's like winning two coin flips. I just rolled a 43. Shit.


gibberishandnumbers

Just got 78 😎


jwr410

Oh noooooo!!! Do you want to split your imaginary dollars with me?


DumpoTheClown

1, duh. Practically guranteed $1000 win. Bird in the hand....


Nojopar

I bid $1 Drew!


AetaCapella

For a second I completely forgot that Bob wasn't the host anymore... it's been almost 2 decades, at this point.


MennionSaysSo

I'll take retired great ones for $200 Alex


ShameMuch

at first i thought wouldnt you always want to pick 1? your practically garunteed money. but then i realized why you pick higher numbers. the higher the number the more payout. personally, i would probably pick something with less risk like 20 instead of the theoretically best possible being 50


randomnickname99

With 2 you have a 99% chance of winning but get double the prize.


procheeseburger

with 3 you have a 98% chance and thrice the prize


FinestVampire

with 4 you have a 97% chance and quadruple the prize


misersoze

Hmmm. I bet it stops there. Probably best to go with 4 then.


ReynoldsHouseOfShred

Exactly as the op states if numbers is LESS and only goes 1-100 youve got an easy win


Altruistic_Major_553

25, high enough that it will solve 90% of my problems, and is low enough there are a lot of numbers after it


procheeseburger

this really is the answer.. TBH 50k wouldn't change my life but 25k could really put me ahead and the odds are much better. That being said I picked 50 and got 58..


DumbbellDiva92

I feel like I would never forgive myself if the computer rolled a 24 though.


Unfunky-UAP

Isn't 50 going to be the highest EV choice? .50*50000=25000 No other choice has a higher EV outcome than that.


Gravier_Prim

Sure but you assume that utility of money is linear which is not true at all in general


Gravier_Prim

For those curious imagine you chose between -80 % chance to win 1,000،000$ or -50 % chance to win 2,000,000$ While the expected value is greater is second case people tend to chose first option because in general you do not consider 2,000,000$ to be twice as good (in terms of hapiness or whatever matters to you) as 1,000،000$


WarcrimeNugget

Use commas. I'm not counting your zeros.


Ill_Ad3517

I think at these scales it's pretty close to linear


iAmBalfrog

Not too sure about that, if you're £100k off a house deposit you're probably aiming for a property too large, bringing home an extra 20-40k likely pays for a wedding/house deposit, I would probably go for 35k and be ecstatic if it comes through.


_Curgin

My thoughts exactly when I chose 30. It's a big part of a new home for us, and more likely than not to come through. Rolled a 36.


info834

50 is highest EV lower reduces variance so the optimum is between 1 and 50 depending on how much money you already have / how much less benefit you get proportionality from the next 1k vs all the ones before it. I went for 30 £21k EV so 16% lower than max EV but 40% lower chance of getting nothing then got 42 on the random number generator.


catsRfriends

EV applies in the long run. You have one chance. Do you need the $1000 right now? How about $2000?


Calm_Leek_1362

This is true. An 80% chance of $20k would be a very strong choice for most Americans. Even 90% for $10k could be life changing for millions of Americans. It could mean clearing a debt or being able to buy a car that would allow them to work. If you have a home and a car and savings, it isn’t as impactful, but so many people have basically nothing, in terms of assets, that the utility of smaller amounts with high confidence is much higher than the effective value of probability * dollar amount. A 90% chance at $10k has a higher effective value than a 10% chance at $90k.


Ill_Ad3517

Well if I make the best EV decisions about this and all the other stuff in my life I'll be better off, even if each decision was unique


catsRfriends

You're conflating EV of life outcomes with EV of this random chance game. If you're homeless and broke and you'll starve to death unless you get some money from this game, does that change things? The EV of the game random variable doesn't change. But your life outcome certainly does.


okiedokieaccount

Agreed, unless some smaller value would have a greater utility, than just having more.  If $15k is what you need for a black market liver/saving grandmas house  then just do that. 50 becomes much more obvious if the deal was, you get to pick 1 number but there’s 100 random numbers chosen and you get paid each time you win . Your EV with 50 is $2.5m and picking 1 you’d expect $99k 


orangesfwr

15. RNG = 39. CHA-CHING!


Gameoverpussy

50 Rng 51 Barely but still there


Caelreth1

Solving this mathematically, the formula for how much money you can expect to get is ((100-x)/100)*x, where x is the chosen number. To find out the maximum expected money, you have to differentiate this, so you rearrange the formula to (100x-x^2)/100, then to x-(x^2/100) to make it easier to differentiate. Differentiating gets you 1-(2x/100), or 1-x/50. The value will be highest when this =0, or x=50. Subbing this back in to the first equation, the expected amount of money is $25000 on average.


AndyC1111

You’ve got some latex issues, bud. But thanks for doing the math.


ScoutAndLout

Too dumb to math here. Monte Carlo code agrees with you, 50 is max expected value according to MATLAB N=100000000 M=100 tic a=randi(M,N,1); b=randi(M,N,1); c=(b>a).\*a; d=\[\]; for i=1:M d(i,1)=sum(c(find(a==i)))/sum(a==i); end toc find(max(d)==d) plot(d) plot is a nice clean parabola, which matches your maths. nice!


KyorlSadei

99. Go big or go home.


Zombie_Peanut

Choosing 20 because 20k pays off all my debts And I rolled a 24! Phew pays not to be greedy 20k for me!!!


Grimey_N_Grumpy

87


Zealousideal-Ad671

50. RNG 98 lol.


TravellingBeard

I'm working on the assumption that ties mean I get the money. * If I pick 1, I'm guaranteed something, at least 1000. * If I pick 26, I have a 25% chance I will get nothing, but 75% chance of getting something nice. * If I pick 51, I have a 50-50 chance of getting nothing or getting something really nice. Hmmm.... All things considered, I'd pick 26 and be okay if I get nothing. I think that's the key part of this solution: what percentage would you be okay getting nothing?


Yverthel

You're 1% off on all your chances. It states "greater than" not "equal to or greater than", so if you pick 1 you still get nothing if they roll a 1.


-pichael_

Right now we don’t know what a tie means. So the guy you replied to has a 50/50 chance of being correct, and they also put a disclaimer that ties being a win were based on assumption. I’m curious towards why you don’t have to assume a tie is loss, but can instead accept it as fact, even though it also doesn’t say “less than or equal to” for the loss conditions, and that the guy you replied to must be wrong, somehow? Genuine question, no accusation, I’m assuming I’m missing something


Tarc_Axiiom

Your assumption is wrong, it's clearly stated in the post. If the RNG rolls **greater** than your number. You do not win ties. > != >=


Awkward-Sir-5794

So, guess .99999999 to get that skrilla


nunya_busyness1984

I go with 27.  It's a good number.


Yverthel

Table Killer says 21. So sad.


cptomgipwndu

I went with 21 and RNG said 9. F.


__Anamya__

Picked 40 got 86 good enough.


OkExperience4487

I got 86 too but I picked 30. You win :P. Well, you win more anyway.


ehhish

20-25


Yverthel

Table Killer says 63. You win! (Nothing because I have no money)


all_fair

20


Yverthel

Table Killer says 4. Wow, it does not like you.


SpiritedAd8229

I chose a low number that would solve a lot of problems for me. 12, figured that was pretty safe so I asked my phone to give me a RNG it gave me 9 fml


TheGrouchyGremlin

$35k Number: 59 I wish I did 50, but oh well. Picked $35k so that I could get a new car, phone, and computer. So my goal was still accomplished


Yverthel

Sounds like a job for The Table Killer. (My solid metal D100) I would choose between 10 and 20 depending on how bold I felt. Tonight I'm feeling particularly bold so we'll go with 20. 36.


storiedsword

I’d say 10. This question depends highly on your current financial situation and how much you can afford to risk losing. If I rolled a 5 after betting on 10, I could accept that it’s just bad luck. If I rolled a 15 after betting on 20, I’d be filled with regret.


Yverthel

Table Killer says 16. Pays to play it safe. Pays in FakeBucks because what is money?


TheRealTofuey

10k


Ill_Ad3517

Well, expected value is highest in the middle at 50 with both ends being worst.   1000 * .99 = 990 100,000 * .01 = 1000 50,000 * .5 = 25,000 So yeah I'll take the coin flip on the 50k.


tau_enjoyer_

Now *this*, this is a great hypothetical question. Good job OP. The payout isn't too ridiculously high, it doesn't have an obvious answer for most people. In fact, I'd be interested to see a distribution curve after a couple thousand people give their answers, or at least a couple hundred. It would be interesting. Maybe somewhere around...25 would be where the curve is highest. So in my own case, I would ere on the side of caution, but also less cautious than if I just said "1," and say 15.


Yverthel

Table Killer has deemed you worthy of hypothetical money and rolled a 50.


Merkilan

33, that is the average percentage of correct answers on a multiple question test if you randomly picked the answers.


Puddlingon

100. The prompt doesn’t say that the number generator is limited to a number 1-100, and it is implied that 100 can be a winner, so there’s at least 101 numbers for the generator to choose from. Logically, if 101 is a possible number, all three-digit numbers are fair game from a computer, so there’s likely at least a roughly 90% chance that the generator spits out a number greater than 100, and I’ll walk away with six figures.


lost-sauce-98

its a bet, if i pick 10, i got a 10% chance of losing. I’m going 10


MonsterTournament

69 And now using a RNG I got 36. F***


Hatchytt

Shit... I'd be really happy right now with 5.


ummaycoc

π^(π)


MisterGoldenSun

39. It's a little below max EV but I'm hoping for a very good return with a pretty strong probability.


NineAndNinetyHours

33. $33k would just about clear all my debts. And rng says... 85! Nice. When can I expect my cheque...?


saint-monkee

20 RNG results: 84 Cool


Longshot1969

Depends on how lucky I feel that day, but 49 would be my highest number, as a gamble of 51-49 is always in my favor. On an unlucky feeling day like 25. I rolled a 95.


GinchAnon

I wouldn't blame someone for going super low. I think I'd probably go at least 20 if not 30. still really quite likely to succeed, but a lot more benefit.


Pandorica_

I probably pick 20ish. Yeah 50 is the mathematically correct pick, but the value of money isn't linear and 20 is a house deposit.


Wickedestchick

I chose 70, got 64 🥺


ReynoldsHouseOfShred

55x2 gamblers in shambles.


ThunderPigGaming

I chose 50, got 66. Imma cash out now.


Vegetable-Bus-1352

75.. rng was 11 I've always been lucky lol


blurryblob

99 full send.


AjaxAsleep

35. Decent odds of payout, not too small. And I rolled a 69; very nice!


Pamplemouse04

lol I said 25 to myself because I thought the odds would be decent and the payout good too. Got 24


Reasonable-Leg-2002

60.


Ishawulf

Rolled a 3 😎 (Chose 34)


superwholockian62

I said 55, generator gave me 56.


ionzy17

I chose 24, rolled a 37. Decent


PureSeduction50

45 felt safe. Rolled a 43...


ShakeCNY

42 And I just rolled a 51. Cool.


acleverlie421

I went with 40 and rolled 78. Ka-ching!


JoeAceJR20

75 Ring 76


KonofastAlt

32


aglimelight

20! Just used a random number generator and got 39 so I’d be safe


chickashady

26 Rng = 28 Phew


BronzeEnt

I'd slap the button out of his hand and say, "You're a billionaire, Sundar." Then leave.


jesusthroughmary

What happens if the random number is your number?


Lucky-Speed3614

2. I like to live dangerously...


Rootibooga

If it's just me, I choose 20.  The increased chance of success is worth the decreased payout for me. . . But that said I would probably break down and say 50 in the spur of the moment, as that's the best odds I'll ever get to make that kind of money in one go. If you're given a 50% chance to make 50 grand, you should take it right? Edit: Random Number Generator give me 67, and I chose 20. Hooray!


Yonefi

32. I added up total of a few big ticket purchase I want but feel selfish making. RNG = 65 Nice…dang now I’m thinking about all the other stuff I could have had. I’m more upset about losing out on 33k than I am happy about getting 32k. :(


Jman15x

Picked 25 got 97


RitmosMC

40. RNG: 7 CRAP


Spicy_Phoenix

And if it lands exactly on that number?


he_who_floats_amogus

50 lets go literally rolled a 51.. what the heck


_Nelots

I’ll pick 100. I like to live dangerously.


Eddyrancid

35- I want to retain strong odds, but it's also a free spin of the wheel, so might as well swing for something that'll make a big difference for me. Edit: rolled a 60, solid call


Solid-Consequence-50

34 Rolled a 19 : /


philter451

19 19k does a lot of work and is statistically on the high end of occuring 


NullTupe

20 gives 80% chance to win 20,000 which is life changing money. I'm comfortable with that level of risk.


Kitchen_Software_638

100. It was never stated the range that the random number generator was pulling from and there are way more than 100 numbers in existence so I would say my odds are pretty good.


KeepBanningKeepJoin

19


Kindle-Wolf

Ten. I have a ninety percent chance of winning $10,000. That's more than enough of a windfall for me


Toreybe

[Guess it doesn't matter.](https://i.imgur.com/YbqvsJt.png)


CohnJena68

I'd go with 50, it's a 50 chance I get $50k. I'd take that.


Mioraecian

I think I'd go with 40. So having a more than 50/50 chance to win a solid sum.


rich8n

The answer is 42.


SmashingPuffins

45 89! Dang it! I was too conservative! Thought about picking 60! Left $15k on the table!


WizardLizard1885

i chose 60  the RNG on my computer chose 19 :/ edit: the next 5 numbers were all under 50.. fuck


chicagotim1

The mathematically correct answer as far as maximizing expected Value is 50, but you could argue going much lower to be optimal if you need a few $x,000


IcarusLP

62


LucienMahikai

2. I either get 1,000 or above, or I get nothing, but loss nothing.


Colts81793

49.99999 is the best option


bob_smithey

Do I get to seed the number generator? Cuz if I do, 1 less than what it picks. lol.


pease461

25


Oreo365

10... and I just rolled a dice and got a 60, so would get 5k


Nuclear_Geek

I'm going with 20. It gives a good chance of winning it, and it's enough to be significant.


FlavoredFN

Op answer: I did this with my mom, I chose 50 she chose 17. I rolled a 73, she rolled a 21.


iofhua

30 If I win I can finally afford a car!


zabumafu369

Is the RNG also restricted to 1-100?


yuri0r

Go for a sum that's noticeable but reasonably high chance, For me that would be 10. 10k would help alot for a long time


say592

I chose 35, random number generator also chose 35. Which I guess is not larger. Fuck.


Bukowskaii

The real answer is you figure out what language it's written in, set the seed to be something where you know the first number will be 100, then choose 99.


rusty_anvile

There's really not a wrong answer here, the expected value is the same for any choice right?


AdmiralCranberryCat

45


TV_H34d

74


SourcePrevious3095

2. No need to be greedy.


lexicon_riot

50 has the highest expected value and is mathematically the correct choice.


Feisty-Albatross3554

Picked 66, rolled 38. Fuck


ChaoticHax

Rolled a fucking 5 lmao


CaptainMan_is_OK

I like 25 for this. That’s a substantial sum, and I have a 75% chance of winning it. 50 is tempting but that’s losing a coin toss and getting nothing. Where to lose 25, you’d have to lose two consecutive coin tosses - not impossible by any means, but much less likely.


EyeSimp4Asuka

I went with 75 found an rng online and it came up with 85...I win


Mister_Oux

10. 10,000 Would be life-changing money for me at the moment. So I'll take the 90% odds.


yaymonsters

I draw my pistol and empty the magazine into that guys face. He's a billionaire right?


xXduyasseneXx

Honestly I’d pick 10 and not greater than 20


mbfunke

I picked 25 and generated 59. I left money on the table, but I’d be stoked about 25k extra.


xczechr

lol, my RNG chose 99 but I chose 22.


BuLlDoGs2212

Picked 30 Rolled 37 I feel I did pretty good


Thedeadnite

What are the parameters of the random number generator, if it is picking between 0-100000 then I’ll pick 100.


Talking_-_Head

40


ASICCC

50, give me the coin toss


tau_enjoyer_

Oof, this is a tough one. Hell, I could pay off my credit cards with just 5K or so. But then I start thinking, what could I do with just 10K, or 20K! Surely saying 49 wouldn't hurt, right? Surely the odds are still in my favor!? I'm reminded of Let's Make a Deal, where almost every single contestant becomes consumed by greed and makes unwise choices, when they could have made a safe choice and walked away with free money.


Imperium_Dragon

45. Let’s see Edit: got an 80


Fenderbridge

60k Rolled a 74. Big money!


TosicamirDTGA

10 RNG 36 Nice.


JustALullabii

Picked 43. Rolled 96. Hyped. At first I was going at this pretty mathematically. And of course winning quite a bit of money would be pretty cool. But the higher you go, the worse your chances, obviously. So in the end I picked a number that felt good. And ended up with 43.


TheTightEnd

I would have gone 25. Enough to be significant while maintaining a good probability. Hit 13, so I lost out.


Supply-Slut

35, good odds but still a lot of money (to me) Whooo I got an 86. I’ll take my $35k in one dollar bills please.


tidyshark12

Does the number generator also have a limit of 1-100? Bc id just pick 100 since it is the largest number and the generator would be limited to, at best, picking the same number but couldn't possibly pick a larger number. Edit: I misread. I'd have lost it all 😭


HadrianMCMXCI

44 cuz fours have always been lucky for me


Serious_Detective877

40, RNG was 43, I’m good


RangeSoggy2788

I got 5 :(


Optimal-Brick-4690

Is this RNG like the one used when I was trying to craft critical in LoTRO? Lol


bibliophile222

I picked 20: decent amount of money, 80% chance of success. Not bad, right? RNG = 5 😕


Annhl8rX

For a reason I can’t explain, I went with 35. My first pull on a random number generator resulted in a 64.


Kilroy898

Well I picked 60, and rolled a 61, so I just barely won.


TouristNo865

I need roughly 60k to get myself on the absolute straight and narrow from where I am. So lets dance! \*Rolls actual RNG\* 53.....well shit.


GingerAndTired

25. In the best case scenario, I walk away with all my debts paid up with a little fun money.


RefrigeratorSlow3943

I was bold and picked 70. RNG said 94. 70k, nice.


_Curgin

30 **Result**: 1d100 (36) **Total**: 36


Ashl3y95

I chose 72 and I rolled a 75


mystere2021

Whats the upper limit of the random number generator? Bc unless its capped at 1000 or something, chances are you can pick 100 and win


sirflappington

Probability wise, 50 and 51 have equal chance of returning the most money so I would just choose either one of those two


BedroomVisible

27. I got a 20...I hate this game lol


Lopsided_Exam_2927

I'd just say fuck it and pick 95.... If I lose, I don't lose anything, but if I win, I get 95k... I didn't walk in with that money, so it's no big deal if I don't walk out with it. ~gamblers logic~


Measurement-Solid

My number was 20. I had to hit the generator 6 times to get something lower, so I like those odds


Elsecaller_17-5

17.5 RNG says 70.


Sinistermarmalade

20,000


allnamesaretaken1020

Wait, so the random number generator can't be limited to the between 1 and 100, so is it 0 to infinity? Are we and the number generator limited to integers? So many questions about the rules....


FunctionSilly8276

I picked 24,since I've never seen it on a random number generator, and for 82


lokiandcoded

20, it clears my debts except mortgage, and it's a 4/5 chance to work


TerrorEra

lol literally got 99. I went with 63


dgrace97

Went for 49 and got an 86. Thankfully I don’t believe in potential profit as lost assets so I’m incredibly happy with 49 thousand free dollars


Impressive-Ladder-37

100. There is nothing in the post that says the random number generated is limited in any fashion. There are a lot more numbers over 100 than under.


Leet_Noob

I think picking the optimal EV response gives me the highest probability of getting a job offer from the CEO of google


jtomark

I choose pi, just to see how the hypothetical apple ceo handles an infinite expression.


toddpacker567

Picked 13 , got 87


bp_516

I pick 49, so I have a better than 50% chance to win.


UnwantedThrowawayGuy

33. I'm happy with 1 in 3 three odds.
