In one of its Spring catalogs, L.L. Bean® advertised footwear on 25 of its 192 catalog pages. Suppose we randomly survey 20 pages. We are interested in the number of pages that advertise footwear. Each page may be picked more than once. Part C answer: X ~ B (20, 25/192) Part E: Is it probable that all twenty will advertise footwear on them? Why or why not? (round your answer to two decimal places.) Part F: What is the probability that fewer than 8 will advertise footwear on them? (round your answer to four decimal places.) Part H: What is the probability that you only need to survey at most 5 pages in order to find one that advertises footwear on it? (round your answer to four decimal places.)
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.
