The Monty Hall Dilemma in Four Parts – #3 A Solution
“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 number 1, and Monty Hall, who knows what’s behind the doors, opens another door, say number 3, which has a goat. Monty Hall then says to you, “Do you want to pick door number 2?” Is it to your advantage to switch your choice of doors?”
A central aspect of this problem is that Monty Hall KNOWS where the car and goats are. When there are two doors left and he opens one of them, he ALWAYS shows a goat. It is not a random 50:50 chance, he ALWAYS eliminates a ‘bad’ door.
