A 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. 35% of respondents identified as Independent, 23% identified as swing voters, and 11% identified as both.
Are being Independent and being a swing voter disjoint, i.e. mutually exclusive?
Draw a Venn or create a table summarizing the variables and their associated probabilities. Which is easier to input? Which is easier to understand?
What percent of voters are Independent but not swing voters? How many voters are in this category?
What percent of voters are Independent or swing voters?
What percent of voters are neither Independent nor swing voters?
Is the event that someone is a swing voter independent of the event that someone is a political Independent?
