According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between six and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month.

A.) Find the probability that the individual lost more than 9 pounds in a month. (Enter an exact number as an integer, fraction, or decimal.)

B.) Suppose it is known that the individual lost more than 8 pounds in a month. Find the probability that he lost less than 12 pounds in the month. (Enter an exact number as an integer, fraction, or decimal.)

C.)
