Question: If X and Y are independent continuous positive random variables, express the density function of (a) Z = X/Y and (b) Z = XY in

If X and Y are independent continuous positive random variables, express the density function of (a) Z = X/Y and (b) Z = XY in terms of the density functions of X and Y. Evaluate the density functions in the special case where X and Y are both exponential random variables.
