Poisson Distribution Calculator

The Poisson distribution is a discrete probability distribution that represents the probability of a certain number of events occurring within a fixed interval of time or space, given a known average rate of occurrence and assuming that the events happen independently of each other.

Mathematically, the probability mass function (PMF) of the Poisson distribution is defined as:

Poisson Distribution

It serves as a fundamental tool in fields such as queuing theory, reliability engineering, epidemiology, and telecommunications, where the occurrence of discrete events is of interest and can be modeled probabilistically.
