Suppose that we have 300 female students out of 1,000 SPSE rst-year students. We
randomly choose 100 students with replacement from the 1,000 students.
(a) Compute the chance that the number of female students in the sample is less than 25.
(b) Compute the chance that the number of male students in the sample is greater than
80.
(c) Compute the chance that we have 30 women in the sample. You may use the normal
approximation or the binomial formula.
