The Poisson Distribution is a probability distribution that describes the number of occurrences of an event in a fixed period of time or space. This statistical model often represents random variables, such as the number of phone calls to a call center or the number of accidents reported in a city. Synonyms for the Poisson Distribution include Poisson Law, Poisson Model, Poisson Process, or simply the Poisson. The concept is named after French mathematician Simeon Denis Poisson, who derived it in the early 19th century. Essentially, the Poisson Distribution enables scientists and researchers to predict the likelihood of specific events occurring within a given interval or area.
