Hi, Can you help me to solve this question? I need help. I don't know how to do that. Please do not chatgpt thanks!

Suppose that X and Y are continuous with joint PDF
f(x,y)
=
[c(1-y) for 0<x<y<1
0
otherwise
where c is a yet-to-be-determined constant.
(a) Find the value of c that makes this a valid joint PDF.
(b) Calculate the probability that X < 1/2 when Y > 2/3.
(c) Find the expected value of X.
(d) Find the expected value of Y.
