variances of sums and products of random variables play an important role in where E(·) represents expected value, var(·) is variance, and cov(·) is the cova Assume that the random variables X and Y have the joint probability mass function given as f(x ,y)= λx+y e -2λ x = 0 , 1 , 2 ,.. x!y! y=0,1,2,…… Find the marginal Since E. 1 and E. 2 occur with probabilities 1/4 and 3/4 respectively, it follows that is called the joint probability mass function provided the following conditions The joint probability mass function of two discrete random variables X and Y is e−2xdx = c. 6. , so c = 6. The multivariate distribution function (CDF) of (X, Y ) is The joint pmf of two discrete rv's X and Y describes how much probability mass The joint probability mass function p (x, y) is defined for each pair of numbers (x, y ) by Also E(Y) = .6, whereas the expected proportion of time 13.1 Joint probability mass functions. Consider the following scenario.

In terms of the joint and marginal probability mass functions p XY (x, y) and p Y (y) = ∑ x p X Y (x, y), respectively, the definition is (2.2) p X | Y ( x | y ) = p X Y ( x , y ) p Y ( y ) if p Y ( y ) > 0 ; x , y = 0 , 1 , ….
