The primary difference between the binomial distribution and the Poisson distribution is that the Poisson is used to describe a continuous random variable and the binomial is used for discrete random variables.

The primary difference is that the binomial distribution is used for discrete random variables with a fixed number of trials, each with two possible outcomes (success or failure), and a constant probability of success. The Poisson distribution, also for discrete random variables, models the number of events occurring in a fixed interval of time or space, given the events occur with a known constant mean rate and independently of the time since the last event. Both distributions are for discrete variables, not continuous.
