For short domestic flights, an airline has three different choices on its snack menupretzels, potato chips, and cookies. Based on past experience, the airline feels that each snack is equally likely to be chosen. If there are 150 passengers on a particular flight, what is the approximate probability that a. at least 60 will choose pretzels for dessert? b. exactly 60 will choose pretzels for dessert? c. fewer than 60 will choose pretzels for dessert?
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.
