The Many Doors problem is a puzzle involving probability loosely based on the Wikipedia article Monty Hall problem which is loosely based on the American game show Let's Make a Deal. That name comes from the show's host, Monty Hall. A widely known statement of the Monty Hall problem is from Craig F. Whitaker of Columbia, Maryland in a letter to Marilyn vos Savant's September 9, 1990, column in Parade Magazine (as quoted by Bohl, Liberatore, and Nydick). The following is a parody which is loosely based on that statement so as to describe the Many Doors problem.
Suppose you're on a game show, and you're given the choice of ten 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 8 other doors, say No. 3 through 10, which all have goats. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?
