public class MontyHallExperiment
extends Experiment
implements java.io.Serializable

This class models the famous Monty Hall experiment. There are three doors; a car is behind one, goats are behind the other two. The player selects a door and then the host opens another door. The player is given the option of keeping her original choice or switching to the other unopened door.
