The joint probability density function of X and Y is given by SK(x² + 6y) 0< I<1 and 0 < y < x f(r, y) = otherwise Compute the covariance of X and Y. Hint: • E[X] = || zf(x, y)drdy I=-00 E[Y] = yf(7, y)dzdy I=-00 y=-00 • E[XY] = | ryf(r.y)drdy I=-00 y=-00 State, with a reason, whether X and Y are independent.
