In statistics, a Poisson distribution is a probability distribution that is used to show how many times an event is likely to occur over a specified period. ... Poisson distributions are often used to understand independent events that occur at a constant rate within a given interval of time.

Why is Poisson distribution important?

We need the Poisson Distribution to do interesting things like finding the probability of a number of events in a time period or finding the probability of waiting some time until the next event.

What is Poisson distribution give its uses?

What is the Poisson Distribution? The Poisson Distribution is a tool used in probability theory statistics. It is used to test if a statement regarding a population parameter is correct. Hypothesis testing to predict the amount of variation from a known average rate of occurrence, within a given time frame.
