Suppose that 65 of families living in a certain country own a laptop and 22 own a desktop computer The Addition Rule might suggest then that 87 of families own either a laptop or a desktop computer What s wrong with that reasoning Choose the correct answer below CCIDE OA The sum of the probabilities of the two given events does not equal 1 so this is not a legitimate probability assignment OB If one family owns a laptop or a desktop computer it can influence another family to also own a laptop or a desktop computer The events are not independent so the Addition Rule does not apply OC The reasoning is correct Thus 87 of families own either a laptop or a desktop computer OD A family may own both a laptop and a desktop computer The events are not disjoint so the Addition Rule does not apply
