Question

LGBARIDDLE:

A man who doesn't want to die is sentenced to two shots in a Russian Roulette. A six-chambered revolver is loaded with two bullets. Then, it will be spun. After spinning, the man will be shot. If the man is still alive, he is given a chance to pick if he wants the revolver to be spun again before pulling the trigger, or just do another shot. What is his best choice?

Answer 1

Let's see who can think the simplest again

Answer 2

spin 1/6< 1/5

Answer 3

btw...the bullets are loaded in successive order...if that matters

Answer 4

yes, even i think spin because there will be 2 bullets in remaining 5 slots after 1st shot.
whereas if u spin, the 2 bullets will be in any 6 slots, so probability wise, he should go for spin.

Answer 5

oh two bullets?
spin 1/3 <2/5

Answer 6

remember: the bullets are loaded in consecutive order...

Answer 7

you have to think simpler

Answer 8

so do u mean to say he should not spin because even if the next slot has bullet, he'd still be alive coz its only 1 bullet he faced instead of 2 required to get killed ??

Answer 9

that's absurd...

Answer 10

why would i do that

Answer 11

ah I got ya... the odds of hitting a chamber with one empty chamber after it are 50% spinning again gives you a 33% chance of getting shot. so don't spin.

Answer 12

at the start you have a 2/6 probability for a bullet. If it gets fired and it's blank, then the probability that the next chamber will have a bullet is what..?

Answer 13

2/5 ?

Answer 14

wrong. it's 2/5 if the bullets are scattered. but like i said, they are put in successive order. So the bullets are adjacent to one another. So the probability would be 1/4

Answer 15

whereas if you spin you get another 2/6 chance for a bullet

Answer 16

actually i didn't get 1/4 part, can u elaborate?

Answer 17

Because there are 4 positions that the 2 bullets can be in if you dont spin, and there are 6 positions if you do spin.

Answer 18

^yes that

Answer 19

I knew it was going to be the multiplication case. I was just trying to clarify what being shot means. Being shot means a bullet actually comes out of the chamber, right?

Answer 20

LOL this made my day: so do u mean to say he should not spin because even if the next slot has bullet, he'd still be alive coz its only 1 bullet he faced instead of 2 required to get killed ??

Answer 21

black dots are loaded

Answer 22

Does being shot means the trigger being pulled or the bullet coming out of the chamber?

Answer 23

being shot means bullet hitting you

Answer 24

Okay

Answer 25

@Skaematik like i said before no

Answer 26

no what

Answer 27

as you can see, after the first shot, there are only four possible positions for a bullet
