Dr. Liu is about to assign grades of A,B,C or D, where D is a failing grade, to his ADM class of 100 students. (a) How many different distributions of grades are possible (by “distribution” we consider only the number of people of each grade)? E.g., A=20, B=30, C=30, D=20 is one distribution. (b) How many different distributions of grades are possible, if we require that no fewer than 80% of the students may pass?
