(a) Assuming that the waiting area always has at least one customer in it. How many customers on average can Mike’s salon process in a day (assuming no problems in utilization, yield, or efficiency)?
(b) Suppose that you need an “average” haircut, and as you walk into the salon you see 3 people sitting in the waiting area. You notice that another person is just sitting down in one of the stylist’s empty chair, and the other stylists are all busy with customers. Assuming you choose to wait, how long would you expect it to be before you are ready to leave the salon?
