Case 6.1
Suppose that you are a contestant on Lets make a deal. Monty has just given you a free trip touring toxic waste sites around the country. He now offers you a trade: Give up the trip in exchange for a gamble. On stage are three curtains, A, B, and C Behind one of them is a brand new car worth $20,000. Behind the other two curtains, the stage is empty. You decide to gamble and select Curtain A. In an attempt to make things more interesting, Monty then exposes an empty stage by opening curtain C (he knows here is nothing behind Curtain C). He then offers you a free trip again if you quit now or, If you like, propose another deal (i.e., you can keep your choice to curtain A or switch to Curtain B). What do you do? To answer the question, try first answering these questions.
1. Before Monty shows you what’s behind curtain C, What is the probability that the car is behind curtain A? What is the probability that the Car is behind curtain B?
2. After Monty shows you what’s behind Curtain C, what is the probability that the car is behind Curtain A? what is the probability that the car is behind Curtain B?
