3. 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 ve students what will be the probability that three students will pass the exam? (25 marks) (hint : binomial probability) (25 marks) 4. From actuary tables, Washington Insurance Company determined the likelihood that a man age 25 will die within the next year is .0002. If Washington Insurance sells 4,000 policies to 25-year-old men this year, what is the probability they will pay on exactly one policy? (hint : binomial probability) (25 marks)
