38.0% of the voting population self-classifies as Christian and voted for Trump.
30.5% of the voting population self-classifies as Christian and voted for Biden.
9.7% of the voting population self-classifies as non-Christian and voted for Trump.
21.8% of the voting population self-classifies as non-Christian and voted for Biden.
1.Put the statistics stated above into a Venn diagram.
(Hint: Do NOT make one oval represent Trump and one oval represent Biden.)
2.Enter the same set of statistics into a contingency chart.

3.What percentage of the population voted for Trump? P(T) = ……………….
4.What percentage of the population voted for Biden? P(B) = ……………….
5.What percentage classifies themselves as Christian? P(C) = …………………..
