5. Suppose X and Y are random variables such that (X, Y) must belong to the rectangle in xy- plane containing all points (x, y) for which 0≤x≤ 3 and 0 ≤ y ≤ 4. Suppose that the joint cumulative distribution of X and Y at any point (x, y) in this rectangle is specified as follows: F(x, y) = xy(x²+y) 156 (a) Use the joint cumulative distribution, F(x, y), to find (P(1 ≤ x ≤ 2,1 ≤ y ≤2) [4] (b) Find the joint probability density function of X and Y
