40 The Diego Street Convenience Store has a single checkout register, with customer arrival distribution shown in the following table:

TIME BETWEEN ARRIVALS (min.)

PROBABILITY 1 0.18 2 0.20 3 0.22 4 0.25 5 0.15 Service time follows a discrete uniform distribution between 1 and 4 minutes. Simulate the arrival of 200 customers to compute the average time a customer waits for service and the probability that a customer waits 3 minutes or longer for service.

Replicate each measure N times to compute its average.
