The densities of independent r.v.s X 1 and X 2 are f 1 (x) = C 1
Question:
The densities of independent r.v.’s X1 and X2 are f1(x) = C1x5e−4x and f2(x) = C2x8e−4x, respectively, where C1 and C2 are constants.
(a) Do we need to calculate these constants in order to find P(X1 + X2 > x)?
(b) Estimate P(X1 + X2 > 3). (Use of software is recommended.)
(c) Write C1 and C2.
