An instructor who taught two sections of engineering statistics last term, the first with 20 students and the second with 35, decided to assign a term project. After all projects had been turned in, the instructor randomly ordered them before grading. Consider the first 16 graded projects.

(a) What is the probability that exactly 10 of these are from the second section? (Round your answer to four decimal places.)


(b) What is the probability that exactly 6 of these are from the first section? (Round your answer to four decimal places.)


(c) What is the probability that at all 16 of these are from the same section? (Round your answer to six decimal places.)

Can you use a calculator for these? If so, how?
