Question
80% of people who purchase pet insurance are women. If 9 pet insurance owners are randomly selected, find the probability that exactly 6 are women.
Answer
Using the binomial formula with n being the number of trials, X being the number of trials meting the desired outcome, p being probability of success and q of failure:
84 × .262144 × .008 = .176
84 × .262144 × .008 = .176
