2.24 Exit poll: Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walke
iVinArrow [24]

Answer:

0.4929 = 49.29% probability that he voted in favor of Scott Walker

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

P(B|A) = \frac{P(B)*P(A|B)}{P(A)}

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Having a college degree.

Event B: Voting for Scott Walker.

They found that 57% of the respondents voted in favor of Scott Walker.

This means that P(B) = 0.57

Additionally, they estimated that of those who did vote in favor for Scott Walker, 33% had a college degree

This means that P(A|B) = 0.33

Probability of having a college degree.

33% of those who voted for Scott Walker(57%).

45% of those who voted against Scott Walker(100 - 57 = 43%). So

P(A) = 0.33*0.57 + 0.45*0.43 = 0.3816

What is the probability that he voted in favor of Scott Walker?

P(B|A) = \frac{0.57*0.33}{0.3816} = 0.4929

0.4929 = 49.29% probability that he voted in favor of Scott Walker
