How would i find the marginal pdfs for this function
[f, XY] (x, y) = 2, y <= x <= 1 , 0 <= y <= 1
What integration limits would i take for the marginal pdf of X say, between y and 1? or 0 and 1. Same thing goes for marginal pdf of Y.
If you want the marginal pdf of X, then you have to integrate with respect to y. And the boundaries for y are 0 to x (since x<=1)

There the y is bigger than x, but all you need to do is switch the variables.
