Assume that the store stocks 30 percent brand A, 50 percent brand B, and the rest are brand X. Assume further that 5 percent of brand A, 25 percent of brand B, and 35 percent of brand X will not provide the number of pages advertised. A customer buys a cartridge at random. If the customer returns the cartridge because it does not provide the number of pages advertised, what is the probability that the cartridge was brand X?

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.
