Unformatted text preview: chosen at random. Find the cumulative distribution function of L , the longer of the two pieces that result. (Hint: Let X be the position of the break. Then X is uniformly distributed on [0,1].) Problem 4. (5 points) Let X have the bilateral exponential density: f ( x ) = 1 2 e x  , < x < . Find the density of X 2 using the cumulative distribution function method. Problem 5. (6 points) Let X and Y be i.i.d, each having as density function the Cauchy density 1 1 1 + x 2 . Find the joint density function of U = 2 X + Y and V = Y. 1...
