1. 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, withp= 0.60 (the probability of a "success") andq= 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? (25 marks) (hint : binomial probability) (25 marks)
