Let the joint pdf of X and Y be f(x, y) = {Kx^2y if 0 ≤ x ≤ y ≤ 1, 0 otherwise}. Find the value of K. Compute P(X > Y). Calculate the marginal distributions of X and Y and check if X and Y are independent.
Added by Terry C.
Step 1
To find the value of K, we need to integrate the joint pdf over its entire support and set it equal to 1, since the joint pdf must integrate to 1 over its support. ∫∫f(x, y) dx dy = 1 Since the joint pdf is only non-zero when 0 ≤ x ≤ y ≤ 1, we can set up the Show more…

Let X and Y have the joint pdf f(x,y) = 6(1-x-y), x+y<1, 0 < x, 0 < y, zero elsewhere. Compute the marginal distributions as well as P(2X+3Y < 1) and E(XY + 2X^2).

Let the joint density of X and Y, fxy(x,y) = {x + y, 0 < x < 1, 0 < y < 1; 0, otherwise. Find the marginal pdfs of X and Y. Are X and Y independent? Are X and Y correlated? Find P(X + Y < 1).
