Homework Answers
(a) Each student can be assigned any of the 5 grades. So there are 5^36 ways of assigning grades.
(b) 15 students can be selected out of 36 students to assign a grade in C(36, 15) ways = 5567902560 ways, and a grade can be selected to be assigned in 5 ways
Probability = 5567902560 / (5 * 5^36) = 5567902560 / 5^37
(c) There are 5 grades that I can get. So, probability that I get an A grade = 1/5
