Using the same probability distribution given in problem 1, would it be unusual for one of my 2019 M146 students to have 8 or more siblings?
P(8 or more siblings) = 0.01639 + 0.03279 + 0.01639 = 0.06557
Hence,
No, it would not be unusual for one of M146 students to have 8 or more siblings because the probability is greater than 0.05.
