1. Do you think that the "most likely" outcome in a binomial distribution is the outcome that will occur most of the time?" For example, what is the "most likely" composition of a four-member committee chosen randomly from a large population that is 50% women and 50% men? What is the probability of the committee composed by two mean and two women? What is the probability of the committee containing one man and three women? What is the probability of the committee containing three men and one woman? 2. What are examples of variables that follow a binomial probability distribution? What are examples of variables that follow a Poisson distribution? When might you use a geometric probability?
