2.7 Swing voters:  A 2012 Pew Research survey asked 2,373 randomly sampled registered voters their political affiliation (Republican, Democrat, or Independent) and whether or not they identify as swing voters. 32% of respondents identified as Independent, 24% identified as swing voters, and 11% identified as both. Draw a Venn diagram summarizing the variables and their associated probabilities.

b) What percent of voters are Independent but not swing voters? %
c) What percent of voters are Independent or swing voters?
%
d) What percent of voters are neither Independent nor swing voters?
