Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walker. They found that 53% of the respondents voted in favor of Scott Walker. Additionally, they estimated that of those who did vote in favor for Scott Walker, 39% had a college degree, while 40% of those who voted against Scott Walker had a college degree. Let S denote the event "voted for Scott Walker" and C denote "Had a college degree". The probability 0.53 above refers to P(S) The probability 0.39 above refers to P(CIS) The probability 0.4 above refers to P(CIS^c) Find: P(C) = 0.3947 P(C and S) = 0.2067 P(C or S) = 0.718 P(C and S) = 0.3947 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? 0.3947

Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walker. They
found that 53% of the respondents voted in favor of Scott Walker. Additionally, they estimated that of those who did
vote in favor for Scott Walker, 39% had a college degree, while 40% of those who voted against Scott Walker had a
college degree.
Let S denote the event "voted for Scott Walker" and C denote "Had a college degree".
The probability 0.53 above refers to P(S)
The probability 0.39 above refers to P(CIS)
The probability 0.4 above refers to P(CIS^c)
Find:
P(C) = 0.3947
P(C and S) 0.2067
P(C or S) = 0.718
P(CC and S) = 0.3947
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? 0.3947
