Question

Quizplus · Accepted Answer

Poisson distribution is commonly used to model arrival rate and service rate in queuing theory because it is a discrete probability distribution that models the occurrence of events over a specified interval of time or space. It is often used to describe the arrival rate of customers or calls to a service center, as well as the service rate of agents serving those customers or calls. The Poisson distribution is also memoryless, which means that the occurrence of an event in the future is independent of when the previous event occurred.
