    The distribution function of the random variable Y is given by

    F(y) = {1 - 9/y2 for y > 3
    0 elsewhere
    }
    Find P(X < 5) and P(Y > 8)

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

    f(x, y) = {24y (1 - x - y) for x > 0, y > 0, x + y < 1
    0 else where
    }

    Find
    a) the marginal density of X
    b) the marginal density of Y
