In a small town, 68% of the people I need television, 72% owned radio, 12% owned neither television nor radio Represent the information on a Venn diagram
What percentage of the population owned television only?

The total of people is the 100%.

68% owns a tv.

72% owns radios.

12% does not own anything.

Now, if we add those, we have:

12% + 68% + 72% = 152%.

This is larger than the 100%, then this means that there is a percentage of people that have both Tv and Radio, this percentage is:

152% - 100% = 52%

We have a surpass because we are adding those 52% two times (because they belong in two different groups)

So, the table is:

68% owns a tv.

72% owns a radio.

12% does not own anything.

52% owns both, radio and tv.

68% - 52% = 16% owns only tv.

72% - 52% = 20% owns only radio.

Then the Venn diagram consist in two circles, one with the 72%, other with the 68%, in such way that the circles have an intersection of the 52%.
