I have a few questions: About 60% of customers will take a free sample offered to them at a grocery store. Of the 60% who take a free sample, about 37% will buy the product they sampled. Suppose that 317 customers walk past a stand offering free samples of chimichangas. What is the probability that 180 or more customers take the free sample? . What is the probability that 200 or fewer take the sample? 3. What is the probability that a random customer who walks by the stand takes a free sample AND purchases some chimichangas? [Hint: Use a simple probability rule.]
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.
