# Exam P Practice Problem 15 – Still More Convolution Practice

_______________________________________________________________

Problem 15A
Find the pdf of $W=X+Y$ where $X$ and $Y$ are independent random variables such that $X$ is uniformly distributed on the interval $0 and $Y$ is exponentially distributed with mean 10.

Problem 15B
Find the pdf of $W=X+Y$ where $X$ and $Y$ are independent random variables such that the pdf of $X$ is $f(x)=2x$ on the interval $0 and $Y$ is exponentially distributed with mean 5.
