Question 1. (Multinomial and multivariate hypergeometric
distribution. See Lecture 26.) In a mixed MathStats class of 30
students, 20 are enrolled only in statistics and 5 are enrolled
only in mathematics: there are 5 students that are enrolled in both
statistics and mathematics.
(a) For each Monday of the 12 weeks of semester, a student from
the class is selected at random to give a class presentation. This
is sampling with replacement: use the multinomial distribution to
find the...
