Researchers collected data on students' class standing and how they did in their English class. Pass Fail Withdraw Freshman 2 14 7 Sophomore 7 18 15 Junior 8 7 1 Senior 13 8 13 10 You can leave your answers as fractions. You also don't have to reduce the fractions. (Ex. a. b. C. d. e. 12 If one student is selected, find the probability that the student is not a junior. D If one student is selected, find the probability that the student failed or the student was a junior. D If one student is selected, find the probability that the student failed. D If one student is selected, find the probability that the student withdrew and the student was a sophomore. B Let A be the event that the student is a junior. Let B be the event that the student withdrew. Are A and B mutually exclusive? Explain. To decide, we have to calculate PM and B) a which in this problem is equal to C] We conclude that A and B are not mutually exclusive 9 , because PM and B) is not equal to 0 a . Let C and D be events such that P(C) = 0.37, P(C or D) = 0.7. The events C and D are mutually exclusive
