2. Let X be a Gamma random variable with parameters A and k E N; i.e., X has density 入kek-le- (k-1)! dx x > 0; fr(x) = 0, otherwise. Let Y be an exponential random variable with parameter A, independent of X. Find the density of X + Y and identify the distribution by name (with values for any parameters).
