The Monte Hall Problem - with the answer

The Monte Hall Problem - with the answer

You're on a game show. It's very simple. There are 3 doors. Behind one is a gold bar and behind the other two there's nothing.

You get to pick a door and keep whatever you find.

All doors are equal to you, so you simply pick door #1.

But before you open the door the game show host (who knows what behind each door) opens door #3 to reveal nothing.

He then asks you if you would like to change your choice from door #1 to door #2.

Do you? Is there any advantage to changing your choice?

Tech Notes:
The answer is yes. In fact, it you change your choice you double your chance of winning. Email me if you want a proof.
