Answer 1

the real answer is about 0.80

Explanation:

so it is asking you about what proportion of the population has a favorite social network, and you see that there is a category that is a no favorite and site A B and C are the sites that are favorites. You add 0.24 + 0.30 + 0.26 and you get 0.80. And that is how you get 0.80
