2. Suppose that the joint CDF of the random variables X and Y is given by:
0,
x < -2 or y < -5
3/8, -2 <r <2 and 5<y < 3
Fx.y(r, y) =
1/2, r2 2 and - 5 <y< 3
1/2, -2 <a < 2 and y 2 3
1,
a 2 2 and y 2 3
Determine the points (b, d) for which P(X b, Y = d) > 0, and evaluate the probabilities at
these points.
