1.* Consider a regular barber shop. Demonstrate that it is a queueing arrangement by describing its components. 2.* Newell and Jeff are the two barbers in a barber accumulation they own and produce. They get two chairs for customers who are discontinuance to start a haircut, so the compute of customers in the accumulation varies betwixt 0 and 4. For n _ 0, 1, 2, 3, 4, the presumption Pn that exactly n customers are in the accumulation is P0 _              1                        . (a) Compute L. How would you narrate the signification of L to Newell and Jeff? (b) For each of the possible values of the compute of customers in the queueing arrangement, indicate how many customers are in the queue. Then compute Lq. How would you narrate the signification of Lq to Newell and Jeff? (c) State the expected compute of customers being served. (d) Given that an mean of 4 customers per hour enter and remain to admit a haircut, state W and Wq. Describe these two quantities in provisions significationful to Newell and Jeff. (e) Given that Newell and Jeff are twin-fellow unswerving in giving haircuts, what is the mean period of a haircut?
