A recent survey examined the use of social media platforms. Suppose the survey found that there is a 0.62 probability that a randomly selected person will use Facebook and a 0.27 probability that a randomly selected person will use LinkedIn. In addition, suppose there is a 0.25 probability that a randomly selected person will use both Facebook and LinkedIn. (a) What is the probability that a randomly selected person will use Facebook or LinkedIn? (b) What is the probability that a randomly selected person will not use either social media platform?
