The time between arrivals 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 arrivals.
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. Compare the results obtained in (a) and (b).
