Question

Let V be the event that a computer contains a virus, and let W be the event that a computer contains a worm. Suppose P(V) = 0.15, P(W) = 0.05, and P(V and W) = 0.03. Round the following answers to two decimal places. a. What is the probability that the computer contains either a virus, a worm, or both? b. What is the probability that the computer does not contain a virus?
