The distributions of students’grades for probability and calculus at a certain university are, respectively, N (65, 400) and N (72, 450). Dr. Olwell teaches a calculus class with 28 and a probability class with 22 students. Write an algorithm to simulate the probability that the difference between the averages of the final grades of
