Answer #1

Let X be the random variable denoting the number of fraudulent assignments out of 18 assignments.

The probability of getting a fraudulent assignment = 14/160 = 0.0875

Thus, X ~ Bin(18, 0.0875)

a. The probability that there are no fraudulent homeworks = P(X = 0) = = 0.1924

b. The probability that there are at least 2 fraudulent homework = P(X 2) = = 0.4755

c. The expected number of fraudulent assignments = np = (18 * 0.0875) = 1.575
