Poisson Distribution

The Poisson distribution is a discrete probability distribution that describes the number of events occurring within a fixed interval of time or space if these events occur with a known average rate and independently of each other. It is a fundamental concept in statistics and is widely used in many fields, including finance, insurance, and quality control.

What is the Poisson distribution?

The Poisson distribution is a probability distribution that describes the number of events occurring within a fixed interval of time or space if these events occur with a known average rate and independently of each other. The Poisson distribution is named after the French mathematician Siméon Denis Poisson, who first studied it in the early 19th century.

The Poisson distribution is often used to model the number of events that occur in a particular time or space interval, such as the number of phone calls received by a call center in an hour, the number of defects in a manufactured product, or the number of goals scored by a soccer team in a game.
