Answer to the problem of the week: The Monty Hall problem

THE MONTY HALL PROBLEM
The Monty Hall problem is a probability puzzle based on the American television game show Let’s Make a Deal.
The name comes from the show’s host, Monty Hall. The problem is also called the Monty Hall paradox, as it is a veridical paradox in that the result appears absurd but is demonstrably true.

Suppose you are on a game show, and you are given the choice of three doors:
Behind one door is a car; behind the others, goats.
You pick a door, and the host, who knows what is behind the other doors, opens another door, which has a goat.
The host allows you to switch your choice to the remaining unopened door.
Should you switch?
