Assume that when adults with smartphones are randomly​ selected, ​38% use them in meetings or classes. If 8 adult smartphone users are randomly​ selected, find the probability that exactly 8 of them use their smartphones in meetings or classes.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

4+3x is the answer

hope you got it
