Everything about Probability mass function

Discrete-variable probability distribution

In probability and statistics, a probability mass function (PMF), discrete probability density function, probability function, or frequency function is a function that gives the probability that a discrete random variable is exactly equal to some value. The PMF is often the primary means of defining a discrete probability distribution, and such functions exist for either scalar or multivariate random variables whose domain is discrete. Wikipedia →
