Question: The time between arrival of cars at the Petroco Service Station is defined by the following probability distribution:

Time between arrivals(min.) Probability

1 .15

2 .30

3 .40

4 .15

1.00

(a). Simulate the arrival of cars at the service station for 20 arrivals and compute the average time between intervals.

(b). Simulate the arrival of cars at the service station for 1 hour, using a different stream of random numbers from those used in (a) and compute the average time between arrivals.

(c). Compute the results obtained in (a) and (b).
