Question: Suppose that X and Y are continuous random variables with the joint probability density function (a) Find k, E(X), E(Y), V(X), V(Y), and cov(X, Y).

Suppose that X and Y are continuous random variables with the joint probability density function

f(x, y) = 3)=((x+7) (x+y) for 0x1.0 sy2 otherwise

(a) Find k, E(X), E(Y), V(X), V(Y), and cov(X, Y). Are X and Y independent?

(b) Find the marginal densities of X and Y.

(c) Find the conditional density of X given Y

f(x, y) = 3)=((x+7) (x+y) for 0x1.0 sy2 otherwise
