Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample space. Suppose that we also have the following. E(X) = -3 E(Y) --9 E(Z) =-5 Var (X) = 11 Var(r)=9 Var(z) =2 Compute the values of the expressions below. E(-3x - 3) - 0 27+ SX Var (-5x) + 2 - 0 =(s2) - 0
