10% of all computers are infected with a computer virus. A company's virus-detection software successfully detects a virus 80% of the time one is present. However, 20% of the time, it says a virus is present when there is not one. Management wants the following probabilities from you: (n = 100) a.) A positive result is accurate: b.) A negative result is accurate:
