Homework Answers
Answer
Given that
P(male total) = 0.41 + 0.200 + 0.131
= 0.471
and
P(Republican male) = 0.140
We have to find the value of P(republican given that male)
using the formula
P(Republican|male) = P(Republican male)/P(male total)
= 0.14/0.471
= 0.297 (rounded to three decimals)

> I think there is an error in the first step. The chart shows .140, .200, .131 but you wrote .41+.20+.131 = with the answer.471. The number 4 and 1 were reversed in your first line. But you calculated as .140+.200+.131
