Suppose that you want to find the probability of getting exactly 2 left-handed people when 4 people are randomly selected. Can the answer be found as follows: Use the multiplication rule to find the probability of getting two left handers followed by two right handers, which is (0.1)(0.1)(0.9)(0.9)? If not, explain why not and show how the required probability can be found.
