a) Set up probability and cumalative possibilty distribution for the variable of car arrivals.
b) Establish random number intervals for the variable.
c) Simulate 15 hours of car arrivals and compute the average number of arrivals per hour. Select the random numbers needed from the first column of table 15.5 chart 1, begining with the digits 52.
d) Compute the expected number of cars arriving using the expected value formula. Compare results obtained from the simulation.
