Do this simulation on Excel.

A bank has one drive-in teller and room for one additional customer to wait. Customers arriving when the queue is full must park and go into the bank to transact business. The time between arrivals and service time distributions are given below: Interarrival Time (minutes) Probability Service Time (minutes) Probability 0 0.09 1 0.20 0.17 2 0.40 2 0.27 3 0.28 3 0.20 4 0.12 4 0.15 0.12 Simulate the operation of the drive-in teller for 20 customers. Assume the first customer arrives at Time 0. How many customers went into the bank to transact business? Use the following table of random numbers: Customer 1 Random Number for Random Number for Interarrival Time Service Time 84 2 91 10 3 72 4 15 94 74 53 17 79 5 6 7 30 92 75 23 30 91 67 8 9 10 89 38 32 94 11 10 9 60 12 13 14 15 16 35 88 79 5 79 84 52 55 30 50 17 10 18 21 49 19 20 53
