A manufacturing firm found 30% of their products needed advertising, 23% needed price reductions, and 11% needed advertising and price reduction. If a product was selected at random, what is the probability that the product does not need advertising or does not need price reduction? 88% 89% 42% 81%
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.
