NO

The outer integral cannot contain variables...

see my change below

When it comes to finding the marginal densities, would I then use 1-x and 1-y as the upper limits?

no, review calc 3

IF you had variables on that outer integral HOW can you end up with a constant? - Oct 28th 2009, 07:56 AMbillym
I understand that about finding the constant. What I mean is, once i have found the constant (3 I think), and want to find the marginal densities, would I then use:

and

or do I have to stick with the initial values? - Oct 28th 2009, 09:42 AMmatheagle
