Explore poisson distributions in this beginner-friendly guide. Learn what they are, how they work, real-world uses, and limitations, from call centers to traffic planning.

A Poisson random variable is the number of successes that result from a Poisson experiment. The probability distribution of a Poisson random variable is called a Poisson distribution.
