2. An album is considered to be "certified platinum" if they sell more than 500,000 copies. Let X be the 400 and Sx x3 total number of copies of an album sold, in thousands. Let f(x) = c- = [500, 0) (a) For what value of c is f(x) a valid density? (b) What is the average number of copies sold by a platinum album? (c) What is the probability that a platinum album sells exactly 650,000 copies? (d) What is the probability that a platinum album sells between 450 and 750 thousand copies?
