According to a survey of college students, the use of social media varies widely according to age. Based on the survey, what is the approximate probability that a non-social media user is an older student aged 282828 and up?
The answer would be 46/219 or 0.21 or 21%. These all could be the possible answers, but written differently (just depends on how you want to write it). And it is because there are 46 non-social media users out of the whole entire total of 219 people, so you just divide 46 by 219 to get your answer.
