Let x and y have the joint density:
f(x,y) = 6/7(x+y)^2 for 0<=x<=1 and 0<=y<=1
a.Find the marginal densities of X and Y. .
b.By integrating over the appropriate regions, find:
For this one, I got the answer for part(i). That is 1-P(X<=Y).
but even for that, why do we take limits for the double integration as 0 to 1 and then x to 2?
