{{Main|Probability distributions}}

Certain random variables occur very often in probability theory because they well describe many natural or physical processes. Their distributions, therefore, have gained ''special importance'' in probability theory. Some fundamental ''discrete distributions'' are the [[uniform distribution (discrete)|discrete uniform]], [[Bernoulli distribution|Bernoulli]], [[binomial distribution|binomial]], [[negative binomial distribution|negative binomial]], [[Poisson distribution|Poisson]] and [[geometric distribution]]s. Important ''continuous distributions'' include the [[uniform distribution (continuous)|continuous uniform]], [[normal distribution|normal]], [[exponential distribution|exponential]], [[gamma distribution|gamma]] and [[beta distribution]]s.
