Here's a simple puzzle that you can google the answer to but try not to.

You are on a game show. There are 3 doors to choose from and behind one door is the prize. The doors are 1, 2, and 3.

You choose door 1.

The host of the game show opens door number 3 to show you that the prize is not there.

Do you benefit from changing your choice to door 2?
