Suppose that X. Y. and Z are jontly. distribsted random variables, that is, they are defined on the same sampie space. Suppose that we also have the following. EX) -3 E(Y) -5 E(Z) = -6 Var (X) - Var (Yr) -35 Var(z) = 17 Compute the values of the expressions below. 2(-1- 2r) -0 Tar) -1-0 Suppose that X.
