A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 92.9% for the medical students admitted through special programs. a) If 12 of the students from the special programs are randomly selected, find the probability that at least 11 of them graduated. b) If 12 of the students from the special programs are randomly selected, find the probability that exactly 9 of them graduated. c) Would it be unusual to randomly select 12 students from the special programs and get exactly 9 that graduate? Explain.
