Homework Statement
Let X and Y be two independent random variables with the same probability density funtion over:
f(x) = {1/a if x € [0,a]
{0 if x=0
Find the density distribution of a) X + Y and b) X*Y
Homework Equations
The Attempt at a Solution
Ok, my initial thoughts are for:
a) That f(X+Y) is simply the product of each of their densities, which would result in 1/(a^2)
b) f(X*Y) is the sum of their individual distributions. i.e. 2/a
This seems a little too simple for me and I think I am looking at it from the wrong perspective.
Any thoughts or advice?
