Default Re: A Microsoft Interview Question (aka basic Bayes\' Theorem)

I don't know Bayes theorem, and I was tempted to say "Yes, spin it again, obviously your chances of killing yourself now are 2/5, where if you spin it will be 2/6." But the "trick question" flag popped up in my mind so I spent a little more time thinking about it. Then I realized that if you just take a second shot, you will have a 3/4 chance of survival, whereas spinning again reduces it to 2/3.
