Consider the following table showing the results of a survey of TV network executives. Opinion of Current Programming Network Satisfied, S Not Satisfied, S Total NBC, N 18 7 25 CBS, C 21 14 35 ABC, A 15 10 25 Total 54 31 85 Suppose one network executive is selected at random. Find the indicated probabilities. (Round your answers to four decimal places.) What is the probability the selected person is from CBS if we know the person is satisfied with current programming?
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.
