Researchers conducted a study to determine whether there were significant differences in graduation rates between medical students admitted through special programs and medical students admitted through the regular admissions criteria. it was found that the graduation rate was 93% for the medical students admitted through special programs in all medical schools. if 10 of the students admitted through special programs are randomly selected, find the probability that at least 9 of them graduated. my math was p(9)+p(10)= 0.387+0.348=0.735 i keep getting it wrong and am at a total loss
