Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 2.0 per hour. It will take Benny an average of 22 minutes to give a haircut. Based on these figures, find the following:The average time a customer waits?

    A new salon with a single barber operates near MIT. The salon provides two kinds of services: Quick Barbering (QB) which takes exactly 9 minutes and Normal Barbering (NB) which takes exactly 15 minutes. On average, the customers who request QB service arrive at a rate of 1 per hour, and the customers who request NB service arrive at a rate of 2 per hour. The two arrival streams follow independent Poisson processes. Because the two arrival streams are independent,...
