An insurance policy is written to cover a loss x where x has density function f(x) =    3 8 x 2 , 0 ≤ x ≤ 2; 0, otherwise. the time (in hours) to process a claim of size x, where 0 ≤ x ≤ 2, is uniformly distributed on the interval from x to 2x. calculate the probability that a randomly chosen claim on this policy is processed in three hours or more.
