A Nielsen survey of teens between the ages of 13 and 17 found that 83% use text messaging and 56% use picture messaging.+ Use these percentages to explain why the two events T = event that a randomly selected teen uses text messaging and P= event that a randomly selected teen uses picture messaging cannot be mutually exclusive. O Because their sum is less than one, they must overlap which means they are mutually exclusive. O Because their sum is less than one, they must overlap which means they are not mutually exclusive. O Because their sum is greater than one, they must overlap which means they are not mutually exclusive. O Because their sum is greater than one, they must overlap which means they are mutually exclusive.
