    Smile Probability

    Suppose 8% of new computers malfunction within the first year. A school purchased 15 computers for its lab.
    a). What is the probability that none of the new computers will malfunction within the first year ?
    b). What is the probability that more than 2 computers will malfunction within the first year ?

    Thank you.
