You are given a die. If you roll a 1 or 4, you get twice your bet. If you roll 2, 3 or 5, then you lose your bet. If you roll a 6, nothing happens. Should you play this game?

hero (hero):

no

OpenStudy (lgbasallote):

why so?

OpenStudy (anonymous):

hm well the chances of you winning are 3/6 and the chances of u losing is 3/6 which is 1/2 u have 1/2 chance to win and 1/2 chance to lose I honelsy wouldnt play but theres an equal chance ull win or lose

OpenStudy (lgbasallote):

why equal chance?

OpenStudy (lgbasallote):

isn't the chance of winning 1/6 + 1/6 = 1/3?

OpenStudy (anonymous):

if u roll a 1,4.or 6 there are thats three sides and overall theres six

OpenStudy (anonymous):

3/6 and same for other numbers then u simplify

OpenStudy (anonymous):

1/2

hero (hero):

Your chances of losing are greater than your chances of winning. On top of that, I know if I played I'd roll a two on the first try because I have bad luck

OpenStudy (lgbasallote):

...why do you win if nothing happens?

hero (hero):

You have three ways of losing and two ways of winning. I don't see it as an equal 50-50

OpenStudy (anonymous):

by i didnt mean winning six is nuthing really to me thts not losing thts why i said equal my mistake.. there are more ways of losing then there is winning soz

OpenStudy (lgbasallote):

but still...the winning and losing prices aer different too...

OpenStudy (turingtest):

let's see... I bet a dollar each time let's imagine I roll 6 times, each time getting a different number and I have $5 and I bet $1 1- I have $7 now 2 -I have $6 3 - I have $5 4 - I have $7 5 - I have $6 6 - I have $6 so I guess I think I should play

OpenStudy (lgbasallote):

that's an odd way of looking at it...

OpenStudy (turingtest):

maybe, but is it wrong?

OpenStudy (lgbasallote):

no idea

hero (hero):

wait,why do you get six more dollars on the first roll?

OpenStudy (turingtest):

I got 2 more, I started with 5

OpenStudy (turingtest):

betting a dollar each time

OpenStudy (turingtest):

PS I suck at probability, hence the funny approach

hero (hero):

Try that with $20 bets and see what happens

OpenStudy (turingtest):

say I have 100 1-140 2-120 3-100 4-140 5-120 6-120 same, I think I should play

OpenStudy (anonymous):

Gambling is Gambling its taking a chance on odds, unless your counting cards..... other than that there is no possible way to choose an outcome theres too much that relies on the outcome such as how its throw whos throwing, if it hits something it will alter the outcome crap like that

OpenStudy (turingtest):

@Vikt0r if the odds are with you then you don't have to look at it like that and you can answer these without using the word "crap" thank you very much

OpenStudy (turingtest):

I think my logic is wrong though...

OpenStudy (turingtest):

I forgot to count what we put in for the bet, so... I have $5 betting $1 each time (imagine the dice come up 1,2,3,4,5,6) 1- 6 2 -5 3 -4 4 -5 5 -4 6- 4 oh I guess I should not play then after all

OpenStudy (turingtest):

I think that is the right answer
