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?

Actually, the script I linked off of the solution to this problem attempts to cover all possibilities by letting you pick the rules of the game. It's actually pretty interesting seeing the results vary based on the rules.
