Question

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.

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?
