WebJoint Probability Mass Function. Let X and Y be two discrete random variables, and let S denote the two-dimensional support of X and Y. Then, the function f ( x, y) = P ( X = x, Y = y) is a joint probability mass … Similarly for continuous random variables, the conditional probability density function of given the occurrence of the value of can be written as where gives the joint density of and , while gives the marginal density for . Also in this case it is necessary that . The relation with the probability distribution of given is given by:
