In probability and statistics, a probability mass function (sometimes called probability function or frequency function[1]) is a function that gives the probability that a discrete random variable is …

Jun 20, 2025 · In probability and statistics, the likelihood of an outcome for discrete random variables is quantified by the probability mass function (PMF), whereas for continuous …

What is a Probability Mass Function? A probability mass function (PMF) is a mathematical function that calculates the probability a discrete random variable will be a specific value.

Probability mass function can be defined as the probability that a discrete random variable will be exactly equal to some particular value. In other words, the probability mass function assigns a …

Dec 28, 2020 · What is a Probability Mass Function (PMF) in Statistics? A probability mass function, often abbreviated PMF, tells us the probability that a discrete random variable takes …

Thus, the PMF is a probability measure that gives us probabilities of the possible values for a random variable. While the above notation is the standard notation for the PMF of $X$, it might …

We will use the common terminology — the probability mass function — and its common abbreviation —the p.m.f. First item basically says that, for every element x in the support S, all …

A Probability Mass Function (PMF) is a function that provides the probabilities of discrete random variables, assigning a probability to each possible value that the variable can take.

The probability mass function (pmf) characterizes the distribution of a discrete random variable. It associates to any given number the probability that the random variable will be equal to that …

Oct 22, 2025 · Probability function that gives discrete random variables probability equal to an exact value is called the probability mass function. The probability mass function is …
