Binomial Distribution: A college finds that 40 percent of all students take a course in statistics. Success is defined as a student not taking a course in statistics. P(Success) = P(student does not take statistics) = 1- .4000 =.6000 . If a group of 8 students are considered: What is the probability that less than 3 students do not take statistics? (use the table in the back of your textbook) (do not round)
