Twо оne-bаrber shоps (i.e., bаrber shop 1 аnd shop 2) sit side by side in the Memorial Union. Each shop can hold a maximum of 3 people, and any potential customer who finds a shop full will not wait for a haircut. Baber 1 charge $20 per haircut and takes an average of 20 minutes to complete a haircut. Barber 2 charges $10 per haircut and takes an average of 10 minutes to complete a haircut. On average, 6 potential customers arrive per hour at each barber shop. Of course, a potential customer becomes an actual customer only if he or she finds that the shop is not full. Assuming that arrival follows Poisson Distribution and haircut time is exponential distributed.
