### What is Meant by Poisson Distribution?

In Mathematics, the Poisson distribution is a discrete probability distribution which results from the Poisson experiment. It classifies the experiment into two different categories, such as success and failure. Generally, the Poisson random variable “x” defines the probability of the success of the experiment. From the average rate of success, the Poisson distribution probability can be easily calculated. Thus, the formula to determine the Poisson distribution function is given by

f(x) = (e λx) / x!

Here,

λ is called the average rate of value

x is called the Poisson random variable
