If the joint probability distribution of X and Y is given by

f(x, y) = c(x2 + y2) for x = - 1, 0, 1, 3; y = - 1, 2, 3 find the value of c.

f(x, y) = c(x2 + y2) for x = - 1, 0, 1, 3; y = - 1, 2, 3 find the value of c.

## Answer to relevant Questions

With reference to Exercise 3.44 and the value obtained for c, Find (a) P(X ≤ 1, Y > 2); (b) P(X = 0, Y ≤ 2); (c) P(X + Y > 2). In exercise f (x, y) = c(x2 + y2) for x = - 1, 0, 1, 3; y = - 1, 2, 3 If the joint probability density of X and Y is given by Find (a) P(X ≤ 1/2 , Y ≤ 1/2 ); (b) P(X + Y > 2/3 ); (c) P(X > 2Y).
