And so let's say that you select door number one, or curtain number one. Then the Monty Hall and Let's Make a Deal crew will make it a little bit more interesting. They won't just show you whether or not you won. They'll then show you one of the other two doors, or one of the other two curtains. And they'll show you one of the other two curtains that does not have the prize. And no matter which one you pick, there will always be at least one other curtain that does not have the prize. There might be two if you picked right, but none of them have the prize.
