A television repair shop repairman finds that the time spent on his jobs has an exponential distribution with mean 30 minutes. If he repairs sets in the order in which they come in, and if the arrival of sets is distributed as Poisson with an average rate of 10 per 8- hour day. What is the repairman's expected idle time each day? a) What is the average number of sets waiting to be repaired? b) How long must a typical customer wait before a set he drops off is ready to be picked up.
