I can't find anything anywhere telling me how to go about it so any help would be very very much appreciated!

Okay, I understand part a) now but after a day of trying, cannot for the life of me understand how to do the rest.

Do I have to integrate to get a cumulative distribution function? And even then, I still don't understand how I can get it in just terms of Y for part b), and what I'm supposed to do for parts c) and d).

Sorry if I'm being stupid, but I really cannot understand what I'm doing at all. (Headbang)(Headbang) - Jul 28th 2010, 05:11 PMmatheagle
You can integrate OUT the rv X to obtain the density of just Y

THEN integrate that from 0 to .5 to answer part (b).
