This Question: 1 pt 17 of 17 (14 complete) This Quiz: 17 pts possible Given that 29% 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 8 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 exacty 8 students have repeated a course is: (b) The probability that fewer than 2 students have repeated a course is: Enter your answer in each of the answer boxes.

Explanation / Answer

a) P(X = 8)

= binom.dist(8, 25, 0.29, FALSE) [Excel Formula]

= 0.160

b) P(Fewer than 2)

= P(0) + P(1)

= binom.dist(1, 25, 0.29, TRUE) [Excel Formula]

= 0.002
