 Pick a box! (Posted on 2002-03-28)
You are shown three boxes, and told that one of them contains a prize. You are then asked to pick one box, and if that box is the one with the prize, you will win it. After picking a box, you are shown that one of the other two boxes is empty, and offered a chance to change your selection.

Should you do this? Would changing your choice to the other remaining box affect your odds of winning? Why or why not?

Look at it this way, the only way to lose if you always switch your answer is if you had chosen correctly the first choice. The odds of that are only 1 in 3, so your odds of winning if you switch must be 2 in 3.
