# What is the difference between a normal distribution, binomial distribution, and a Poisson distribution?

While in Binomial and Poisson distributions have discreet random variables, the Normal distribution is a continuous random variable. Poisson and Normal distribution are special cases of Binomial distribution.

While in Binomial and Poisson distributions have discreet random variables, the Normal distribution is a continuous random variable.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
