ves as Democrats, 45% as Independents, 21% as Republicans, and 2% as Other.23 When asked, "Should the government in Washington do everything possible to improve the standard of living of all poor Americans?," 23% of the Democrats, 18% of the Independents, 4% of the Republicans, and 15% of Others agreed. Given that a person agrees that the government in Washington should do everything possible to improve the standard of living of all poor Americans, use Bayes’ rule to find the probability the person thinks of him- or herself as a Democrat.
Probability that a person thinks of himself as Democrat = P(A)= 0.32
Probability that a person agress that the govt. in Washington should do everything possible to improve the standard of living of poor= P(B)
Probability that a Democrat agress that the govt. in Washington should do everything possible to improve the standard of living of poor P(A ∩ B) = 0.23
