MONTY HALL ANALYSIS In five of my statistics classes, 101 pairs (or teams) of students each played 18 rounds of the Monty Hall game. If X represents the number of “wins” among the 18 rounds played under the “switching strategy,” then X ± Bin n = 18, p = 2 3 ± ² ³ ´ µ . Let’s compare the theoretical binomial probabilities for the possible numbers of wins with the relative frequencies that we obtained for our 101 teams. Note : I wish that we had many more than 101 teams; then, the correspondences may have been more impressive!
