The above Venn diagram represents survey respondents from a recent political poll. Based on the respondent's political affiliation, they were classified into group
What percentage of the respondents were classified into both groups?
The common portion of this Venn diagram represents the percentage of respondents that were classified into both groups. In order to calculate the percentage that represents the amount of respondents classified into both groups, first find the sum of group 
and group 
. Then subtract that quantity from 
percent.
The solution is:
