# Population variance

In a California community college, 60% of students will transfer to a college in the CSU system. The number of students in a sample who will transfer follows a binomial distribution.

If eight students are randomly selected, find the population variance σ

If eight students are randomly selected, find the probability that three or fewer of these students will transfer to a college in the CSU system.
