... Let us use the same example with the bakery data. Arrival rate is said to be 20 customers per hour. Interarrival mean, or the Exponential mean, is 1 / arrival rate. Therefore, for this example, the interarrival mean is 1/20 hours per customer arrival. To find the probability that a customer arrives ...
