I just need a guide to this problem... found in one of the books in the library...(adsbygoogle = window.adsbygoogle || []).push({});

Given the joint pdf f(x,y) = 2e^[-(x+y)] where 0 < x < y, y > 0

find P(Y < 1 / x < 1). Note that "/" means given that.

I got the formula when P(a < Y < b / X = x) is given, i.e., in terms of the integral from a to b of f(y/x)dy. But how about this? Is there a formula to transform this? =) The answer is in the book... so I want to know how to begin with...
