The percent of internet users who neither download nor share music files. Also, to draw a Venn diagram that displays the information.
Answer to Problem 47E
The required percent of internet users who neither download nor share music is 62%.
Explanation of Solution
Given information:
Proportion of internet users who download music files online = 29%
Proportion of users who share music from their computers = 21%
Proportion of users who both download and share music = 12%
To find the percent of internet users who neither download nor share music files, we use subtraction method.
To find the percent of internet users who download music but do not share, subtract 12% from 29%.
To find the percent of internet users who share but do not download, subtract 12% from 21%.
To find the internet users who neither download nor share music, subtract 17%, 12% and 9% from 100%.
The Venn diagram that displays the given information is shown below:
In the diagram the internet users who download music is shown on the left and the users who share music is shown on the right.
Hence, the required percent of internet users who neither download nor share music is 62%.
