Monty Hall Stats

Calculate the stats of the Monty Hall problem.

What is the Monty Hall problem?

Suppose 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. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?

• Wikipedia

Your intuition might say there would be no reason to switch the doors since the odds should be 1/2 of recieving the car since there would only be 2 doors left, but that assumption would be wrong as the chance is actually locked in at the begining of the game, so keeping the door would result in a 1/3 chance of recieving the car, while switching the door results in a 2/3 chance of winning the car.
