Dirty Harry places two bullets in random chambers of the six-bullet cylinder of his revolver. He gives the cylinder a random spin and says "Feeling lucky?" as he holds the gun against your heart. (a) What is the probability that you will get shot if he pulls the trigger? (b) Suppose he pulls the trigger and you don't get shot. What is the probability that you will get shot if he pulls the trigger a second time? (c) Suppose you noticed that he placed the two shells next to each other in the cylinder. How does this change the answers to the previous two questions?

A Russian gangster kidnaps you. He puts two bullets in consecutive order in an empty six-round revolver, spins it, points it at your head, and shoots. *click* You're still alive. He then asks you, "do you want me to spin it again and fire or pull the trigger again right away?" For each option, what is the probability that you'll be shot?
