Suppose that you are looking for a student at your college who lives within five miles of you. You know that 50% of the 197 students do live within five miles of you. You randomly contact students from the college until one says he or she lives within five miles of you. Find the probability it will take 6 of them until one says he or she lives within five miles of you and 9 of them until one says he or she lives within five miles of you.
