I am working on studying for a probability exam and I just came across conditional variance, but I can't find anything in my materials for how to solve it.(adsbygoogle = window.adsbygoogle || []).push({});

If I want to find the conditional variance of Y given that X=x, or Var[Y|X=x], how would I solve it? I am given a continuous distribution function of:

f(x,y) = 2x, for 0<x<1, x<y<x+1

otherwise 0.

How do I set up this question?

Thanks!
