The Poisson distribution is often used to model the arrival pattern or arrival rate of events, such as customers arriving at a store or patients arriving at a hospital. It is a discrete probability distribution that is commonly used in queuing theory and operations management. The Poisson distribution is characterized by a single parameter, λ, which represents the mean arrival rate or expected number of events per unit time.
