On a certain chemistry class, a professor has observed that, on her past final exams, 72% of the students pass the final exam. Assume that students in the current class perform similarly. a. If the professor currently has a large lecture class of 125 students. What is the ESTIMATE probability that 75 to 100 students will pass the final exam? b. In addition to the large lecture, if the professor has an evening class of 30 students, what is the ACTUAL probability that 18 to 22 students will pass the final exam?
