5. The random variable Z is defined to be the sum of two independent random vari- ables, X+Y. The random variable X has an exponential distribution with mean 3. The PDF for the random variable Y is fy(x) = 0 {} 0 2x < 0, X 0 x > 1, x 1, Use a convolution to determine the PDF of Z. (Evaluate the integral and do not leave your answer as an integral.)
