    Conditional Probability Quality Control

    The quality control inspector for a computer company either accepts or rejects microprocessors as a result of testing a sample of the items in a shipment. The inspector's previous performance indicates that she has:

    accepted 98% and rejected 2% of all shipments that turned out to be good.
    Accepted 94% of all shipments even though 5% of the shipments are known to be inferior

    a) Find the probability that a good shipment is rejected
    2% - i got that

    b) Find the probability that an inferior shipment is accepted
    The back of the book said 8%
