The random variable \( X \) associated with a Poisson process is discrete and therefore the Poisson distribution is discrete. Poisson probability distribution is used in situations where events occur randomly and independently a number of times on average during an interval of time or space.

It is well known that under certain conditions, binomial distributions converge to Poisson distributions. MathOverflow is a question and answer site for professional mathematicians. The question is the following: can we assure that the sequence does NOT converge in distribution to a Poisson? A Compound Poisson Convergence Theorem Wang, Y.
