How do I construct a Joint PMF from 2 separate PMFs?

WebProbability mass function (pmf) of a single discrete random variable X specifies how much probability mass is placed on each possible X value. The joint pmf of two discrete random variables X and Y describes how much probability mass is placed on each possible pair of values (x, y): p (x, y) = P(X = x and Y = y) WebY as the marginal PMFs, to distinguish them from the joint PMF. The example of Fig. 2.11 illustrates the calculation of the marginal PMFs from the joint PMF by using the tabular method. Here, the joint PMF of X and Y is arranged in a two-dimensional table, and the marginal PMF of X or Y at a given value is obtained by adding the table entries ...
