5. Roughly 26% of the smartphones (in the US) run on iOS, 72% on Android, and 2% on another operating system. Suppose that 45% of the smartphones running on iOS, 60% of those running on Android, and 25% of those running on another operating system are infected by a virus. (3.) Draw the tree diagram for this problem. (b) What is the probability that a randomly selected smartphone is infected by a virus? (c) Given that a randomly selected smartphone is infected by the virus, What is the proba- bility that it runs on Android? (d) Given that a randomly selected smartphone is not infected by the virus, what is the probability that it does not run on iOS
