4. According to the Red Cross Blood Organization, the blood type most requested by hospitals is type O. About 45% of the North American population has blood type O. a) If 4 blood donors are selected at random, create a probability distribution histogram to show the probability of x, where x represents the number of donors with blood type O. b) If 7 blood donors are selected at random, what is the probability that exactly 3 of them will have blood type O. c) If 10 blood donors are selected at random, what is the probability that exactly 6 will have other blood types? d) If 15 blood donors are selected at random, what is the probability that at least one will have blood O?
