An important discrete probability distribution is the Poisson distribution.1 We examine it because of its key role in complementing the exponential distribution in queuing theory in Chapter 12. The distribution describes situations in which customers arrive independently during a certain time interval, and the number of arrivals depends on the length of the time interval. Examples are patients arriving at a health clinic, customers arriving at a bank window, passengers arriving at an airport, and telephone calls going through a central exchange.
