Support of a discrete variable For discrete random variables , it is the set of all the realizations that have a strictly positive probability of being observed. Example If a discrete random variable has probability mass function its support, denoted by , is

variable is a random variable for which the support is an interval of values. Discrete Random Variable – For a discrete random variable, it is useful to think of the random variable and its pdf together in a probability distribution table. Example: A fair coin is tossed three times.

Discrete random variable. by Marco Taboga, PhD. A random variable is said to be discrete if the set of values it can take (its support) has either a finite or an infinite but countable number of elements. Its probability distribution can be characterized through a function called probability mass function.

Given a random experiment with sample space S, a random variable X is a set function that assigns one and only one real number to each element s that belongs in the sample space S. The set of all possible values of the random variable X, denoted x, is called the support, or space, of X.

Another random variable may be the person's number of children; this is a discrete random variable with non-negative integer values. It allows the computation of probabilities for individual integer values – the probability mass function (PMF) – or for sets of values, including infinite sets.

This section covers Discrete Random Variables, probability distribution, Cumulative Distribution Function and Probability Density Function. A probability distribution is a table of values showing the probabilities of various outcomes of an experiment.. For example, if a coin is tossed three times, the number of heads obtained can be 0, 1, 2 or 3.

Let X be a discrete random variable with support S 1, and let Y be a discrete random variable with support S 2. Let X and Y have the joint probability mass function f(x,y) with support S. Then, the probability mass function of X alone, which is called the marginal probability mass function of …
