(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Say X and Y are independent random variables with densities f and g, respectively:

f(x) = e^(-x) if x > 0 and 0 if x < 0

g(y) = 2e^(-2y) if y > 0 and 0 if y < 0

Calculate a density function for Y/(X+1)

2. Relevant equations

Change of variable?

Convolution?

Calculating distribution function?

3. The attempt at a solution

I know convolution lets you find the addition of densities, but dividing them is something altogether new for me, and I am not sure how to even approach it.
