Discrete probability distributions These distributions model the probabilities of random variables that can have discrete values as outcomes.. 7 Types of Discrete Probability Distributions and Their - Medium Normal 5. A random variable is actually a function; it assigns numerical values to the outcomes of a random process. Whereas a continuous distribution implies that X can take on an infinite (uncountable) number of different values. Probability distributions are of two types: 1. Geometric Distribution. Different Types of probability distribution - Statanalytica Binomial Distribution. They are as follows: A random variable X is said to have a discrete probability distribution called the discrete uniform distribution if and only if its probability mass function (pmf) is given by the following: P(X=x)= 1/n , for x=1,2,3,.,n. 3. Discrete Distribution Example Types of discrete probability distributions include: Poisson Bernoulli Binomial Multinomial Consider an example where you are counting the number of people walking into a store in any given hour. 1.
