Sick computers: Let be the event that a computer contains a virus, and let W be the event that a computer contains a worm. Suppose P(V) 0.31, P(w)=0.4, P(V and W)=0.07. (a) Find the probability that the computer contains either a virus or a worm or both. (b) Find the probability that the computer does not contain a worm. Part 1 of 2 (a) Find the probability that the computer contains either a virus or a worm or both. The probability that the computer contains either a virus or a worm or both is Part 2 of 2 (b) Find the probability that the computer does not contain a worm. The probability that the computer does not contain a worm is X X
