Suppose that two random variables X and Y have the joint PDFfXY(u, v) = {60(u^2)v u ≥ 0, v ≥ 0, and u + v ≤ 1, 0 otherwise.(a) Are X and Y independent?(b) What is the marginal distribution fX(t)?(c) What is Pr[X ≥ Y]? (To set up the right integral, it might help you to draw the rangeof (X, Y) in the uv-plane and identify the region within that range where u ≥ v.)

Suppose that two random variables X and Y have the joint PDF
fXY(u, v) = {60(u^2)v u ≥ 0, v ≥ 0, and u + v ≤ 1,
0 otherwise.
(a) Are X and Y independent?
(b) What is the marginal distribution fX(t)?
(c) What is Pr[X ≥ Y]? (To set up the right integral, it might help you to draw the range
of (X, Y) in the uv-plane and identify the region within that range where u ≥ v.)
