In a particular community, 70% of the voters are Democrats, and 30% are Republicans. Sixty percent of the Democratic voters and 40% of Republican voters favor the incumbent. What is the probability that a randomly selected voter from this community favors the incumbent?
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.
