Monty Hall was the host of a popular game show called "Let's Make a Deal." Three closed doors hide the
 contents of three "prizes." There is a legitimate prize behind one of the doors and a dud prize behind
 the other two. Monty chooses the prize door randomly.
_ 
Initially, the contestent is asked to choose one of the three doors.
_
Then, Monty then opens one of the other two doors. Monty knows where the prize is located.
 If the prize is behind the contestent's initial choice, Monty would randomly open one of the
 other two doors. On the other hand, if the prize was not behind the door initially chosen
 by the contestent, Monty would always open door that does not hide the prize. In other words,
 at this point in the game, Monty would never open the door that hides the prize.
_ 
Next, the contestent was given the opportunity to stick with his/her inital choice or switch.
