A Microsoft Interview Question (aka basic Bayes' Theorem)

[rt1]

i drew this out on a piece of paper and it seemed rather easy to me. and im not smart.

your friend shot and hit a blank. that means that no bullet was about to fire so therefore the trigger wont be on the next bullet or the next empty slot. leaving 1 bullet and 3 empty slots (4 slots total) left for the next pull. 1/4 you kill yourself, 3/4 you live.

if you choose to respin, you land on a bullet 2/6 times or 1/3 of the time.

so, i dont respin, i just pull the trigger.
