Suppose the X1 and X2 denote a random sample of size 2 from a gamma distribution, (see attached file). This is Gamma distribution.

a) Find the pdf (probability density function) of Y = (X1 + X2)^1/2

b) Find the pdf (probability density function) of W = X1/X2

In this problem you have to find for the pdf in part a and b, they don't ask the pdf of both together. You must find the pdf of Y and pdf of W.
