2) About 35% of the population has blue eyes. If a person is randomly selected, what is the probability that he or she does not have blue eyes? If four different people are randomly selected, what is the probability that they all have blue eyes? Would it be unusual to randomly select four people and find that they all have blue eyes? Why or why not? 35%-1.5%--1.5% is small and if you did the test 200 times you only get 3 cases where this would happen, yes its unusual 3) You are trying to develop a strategy for investing in two difference stocks.
