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

Concept explainers

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

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
