A group of people conducted a study of a new store. Management stated 15 percent of the customers that visit do no make a purchase. A new chain is considering locating in the near area. The group stops 16 potential customers for a survey. Using the binomial probability distribution. a) What is the probability that exactly four customers do not make a purchase? b) What is the probability that at least two customers do not make a purchase? c) What is the probability that at most one customer does not make a purchase?
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.
