The Monty Hall problem came from a game show where celebrities either won a car or a goat Monty Hall would ask a celebrity to pick one of three doors. Monty then opened one of the doors that had a goat in and wasn't the celebrity's revealing a goat. he would offer the celebrity a choice to stay with their door or switch to the other.
