OK, heres a probability one for you. You are playing a game show and the host asks you to pick your prize. There are three doors you can pick and one of them has a prize behind it. The other two have chickens (which, I admit, would be a prize to some people but not to most).

He asks you to guess so you pick one. He then opens one of the other doors to reveal a chicken.

He asks you if you are still sure.

On the basis of pure probability should you stick or change?



joint little late, but this is actually something I studied in Calc III

the answer is should change, because it doubles the chances of getting a prize

pick randomly is: 1/3
switch is: 2/3

so always switch
