Poisson Distribution as a Special Case of Binomial Distribution

I wondered that what's the difference between Poisson and Binomial Distributions.

Here's the difference, a very slight difference.

and actually, Poisson is a special case of Binomial distribution!

Poisson Distribution

• n (the number of trials): huge
• p (the probability of success): small
