According to a study by Dr. John McDougall of his live-in weight loss program, 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. 1). Find the probability that the individual lost more than ten pounds in a month. 2). Suppose it is known that the individual lost more than ten pounds in a month. Find the probability that he lost less than 12 pounds in the month. 3). P(7 < x < 13|x > 9) = __________. State this in a probability question, draw the picture, and find the probability.
