John Poisson

John Poisson was a French mathematician known for developing the Poisson distribution, a statistical tool used to model the number of times an event occurs within a fixed interval or area, especially when these events happen randomly and independently at a constant average rate. For example, it can be used to predict the number of emails received per hour or the number of radioactive particles emitted by a source in a given time. The Poisson distribution helps in understanding the probability of rare events and is widely applied in fields like telecommunications, insurance, and physics.
