Suppose that the probability of passing an exam is 60 percent, so the probability of failing the exam is 40 percent. This represents a binominal experiment, with p = 0.60 (the probability of a “success”) and q = 0.40 (the probability of a “failure”). If the class has five students what will be the probability that three students will pass the exam? (hint : binomial probability)
