Given that 28% of college students have repeated a course to improve their grade, in a sample of size n = 25, use the Binomial Probability formula to find: (a) the probability that exactly 12 students have repeated a course. (b) the probability that fewer than 2 students have repeated a course. Round answers to the nearest thousandth (3 decimal places). (a) The probability that exactly 12 students have repeated a course is: (b) The probability that fewer than 2 students have repeated a course is:
