Question 1175539: 2.24 Exit poll: Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walker. They found that 57% of the respondents voted in favor of Scott Walker. Additionally, they estimated that of those who did vote in favor for Scott Walker, 32% had a college degree, while 47% of those who voted against Scott Walker had a college degree. Suppose we randomly sampled a person who participated in the exit poll and found that he had a college degree. What is the probability that he voted in favor of Scott Walker?

Of the 57% who voted in favor, 32% had a college degree.

Of the 43% who voted against, 47% had a college degree.

The probability that a person voted in favor, given that he had a college degree, is

You can do the calculation and round as needed.
