Homework Statement
X & Y are independent r.v.s with uniform distribution between 0 and 1.
Z= X/(1+Y)^2
find E[Z].
Homework Equations
The Attempt at a Solution
Here is what I did.
E[Z]= E[X]*E[1/(1+Y)^2]
E[X]=1/2
E[1/(1+Y)^2]=?
I think that once I know the distribution of (1+Y)^(-2), I'll be able to find the answer. Is it 1/(1+Y)^2~ U(1,2) ?
