The Monty Hall problem
There are three curtains, an announcer (Monty) and a player (you). One
of the curtains contains a valuable prize and the other two are empty:
only Monty knows where the prize is. You win the prize if you
guess correctly which curtain contains the prize. Initially, you
select a curtain. Then, Monty opens an empty curtain that
you did not choose. Having eliminated that curtain from contention,
Monty offers you the option to select the remaining third curtain as a
final choice. Should you switch?
