44 A customer service counter at a local bookstore is normally staffed by a single employee. The probabilities of arrival times and service times are shown in the following table:

TIME BETWEEN ARRIVALS

(min.)

PROBABILITY SERVICE TIME

(min.)

PROBABILITY 1 0.07 1 0.07 2 0.25 2 0.24 3 0.23 3 0.28 4 0.26 4 0.28 5 0.19 5 0.13 Simulate the arrival of 100 customers to compute the average number of customers in line and the probability that a customer will have to wait 3 or more minutes for service to begin. Replicate each measure N times to compute its average.
