WebbE[T]=0.6 · 2 5 +0.4 · 2 30 = 4 15 hours. However, it is wrong to calculate the mean of the speed V , E[V ]=0.6 · 5+0.4 · 30 = 15 miles per hour, and then claim that the mean of the time T is 2 E[V ] = 2 15 hours. To summarize, in this example we have T = 2 V, and E[T]=E " 2 V #!= 2 E[V ]. 2.5 JOINT PMFS OF MULTIPLE RANDOM VARIABLES WebbDefinition 5.1.1. If discrete random variables X and Y are defined on the same sample space S, then their joint probability mass function (joint pmf) is given by. p(x, y) = P(X = x and Y = y), where (x, y) is a pair of possible values for the pair of random variables (X, Y), and p(x, y) satisfies the following conditions: 0 ≤ p(x, y) ≤ 1.
