Coined by American statistician Steve Selvin in 1975, named after Monty Hall, former host of the American television game show Let's Make a Deal.
Noun
Monty Hall problem (plural Monty Hall problems)
- A brainteaser regarding probability, in which a game show contestant picks a door to win a prize. One door conceals a car; the other two conceal goats. After the contestant picks a door, the host opens one of the two remaining doors which reveals a goat. Counterintuitively, it is then in the contestant's interests to switch to the remaining door.

- In the Monty Hall problem, it is one thing if your initial choice is incorrect and you lose the game by failing to switch. It is quite another to be sitting on the correct door and then lose the game by moving away from it.
