Personal electronics, such as smart phones (defined as P} and tablets (defined as T], are getting more advanced all the time and consumers are demanding more functionality. Manufacturers of these personal devices experience problems in the production processes when the robots that assemble the components fail and need either a major adjustment {defined as M) or a small adjustment (dened as 5). A major adjustment results in the shutdown of production for two days while a small adjustment causes a one-dayr shutdown. The Quality Production manager has noted the following: - probability the personal electronic device production process needs a major adjustment is 0.10 - probability that a smart phone is manufactured is 0.40 - probability the personal electronic device needs a major adjustment and a smart phone is manufactured is 0.05 (b)What is the probability that a randomly selected personal electronic device needs a major adjustment, or it is a tablet
