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 (Y)=-7 E(z) = 4 Var(Z) = 6 E (X) = 0 Var(X) = 42 Var(Y) = 39 Compute the values of the expressions below. E (4Y-1) = 0 %3D ? ()- 0 3X-Z E -1-Var(Y) = 0 E(2x²) = 0
