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
