if records show that the probability of failing with a F is P( probability of student receiving F). What is the probability that at most 2 of 15 fail the course? if records show that the probability to get a B is P( probability of student receiving B). What is the probability that exactly 4 students of 15 will have a B grade? if records show that the probability of selecting a grade A student for the first time in either the 2nd or 3rd selection? grades for 15 students: 9A's, 2B's, 1C, 0D, 3F's
