    Also the following problems on Bivariate Distributions.

    1. Suppose the joint p.d.f. of a pair of random variables on the rectangle 0 < x < 2, 0 < y < 1 is given by f(x,y) = 1/2. Compute Prob(X > Y).

    2. Suppose the joint p.d.f. of a pair of random variables on the rectangle 0 < x < 2, 0 < y < 1 is given by f(x,y) = xy. Compute Prob(X > Y)

    3. Suppose the joint p.d.f. of a pair of random variables on the first quadrant 0 < x, 0 < y is given by f(x,y) = 6exp(-(2x+3y)) (exp(x) = e^x). Assume a > 0.
    Compute Prob(X > a), Prob(Y > a), Prob(min(X,Y) > a), Prob(X > Y)

    4. Suppose the joint p.d.f of n-random variables x(k), k = 1,...,n on the region 0 < x(k) < 2 for k = 1,...,n is f(x) = 1/(2^n). Let Y = x(1) + x(2) + .... + x(n)
    Compute E(Y) and E(Y^2).
    Hint. For independent random variables we have the means and variances add.

    Please don't look at answers till you have done them.
    Ans. #1 3/4, #2 7/8, #3 exp(-2a), exp(-3a), exp(-5a), 3/5,
    #4 E(Y) = n E(Y^2) - E(Y)^2 = variance = n/3 so E(Y^2) = n*n + n/3
