this is a very general question Suppose i have that $$cor(X,Y)=\rho >0$$ I am trying to estimate $$p(X<2Y)$$ using either conditional distribution of X, joint distribution of X,Y ... I just really dont know which one you are meant to use in that case.

There is more than one way to do it. If you have the joint density function $f_{X,Y}(x,y)$ then you perform a double integral over only the portion of the domain that satisfies $X < 2Y$.
I don't see a way to use correlation without knowledge of the distribution and its domain.
