Monte Hall Monte Carlo

By Espen Gaarder Haug, 1998

Today :

In the famous Monte Hall game the player choose one door out of three closed doors. Behind one of the doors is a prize. Then the game show host open a certainly empty door. The host offers you the chance to switch door. Will you ?

Simple probability calculations shows that changing the door always increase the probability of winning. The probability of winning actually doubles (goes from 1/3 to 2/3).

Here you can try out yourself by running Monte Carlo Simulations on the Monte Hall problem.
