Assume that the weight loss for the first two months of a diet program has a uniform distribution over the interval 6 to 12 pounds. Find the probability that a person on this diet loses between 9 and 12 pounds in the first two months.
a. 1/4 b. 1/2 c. 1/3 d. 2/3
9 to 12 is half of the full interval. Since the distribution is uniform, the probability is 1/2
I am surprised there are no zeros or weight gains.
