EXER 6.1
Suppose that the joint CDF of the random variables X and Y is given by:
0,
x < -2 or y < -5
3/8, -2 <x < 2 and – 5 < y < 3
Fx,y(x, y) =
1/2, x > 2 and – 5 < y< 3
1/2, -2 <x < 2 and y > 3
1,
x > 2 and y > 3
Determine the points (b, d) for which P(X = b, Y = d) > 0,
and evaluate the probabilities at these points.
