Abstract: Game to play monty hall problem

Full Description: Imagine you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat (obviously, host always opens the door with a goat). He then says to you, "Do you want to pick door No. 2?"

Is it to your advantage to switch your choice?
