A cable car starts off with n riders. The times between successive stops of the car are independent exponential random variables with rate λ. At each stop one rider gets off. This takes no time, and no additional riders get on. After a rider gets off the car, he or she walks home. Independently of all else, the walk takes an exponential time with rate μ.
(a) What is the distribution of the time at which the last rider departs the car?
(b) Suppose the last rider departs the car at time t. What is the probability that all the other riders are home at that time?
