.Accuracy in taking orders at a drive-through window is important for fast-food chains. Accuracy is defined as the percentage of orders that are filled correctly. In a recent year, the percentage of orders filled correctly at Wendy’s was approximately 90%. Suppose that three (3) customers visit the drive-through window at Wendy’s and place an order independently. What are the probabilities that: (Binomial) a) All three will be filled incorrectly. So Find P(X = 3 / n = 3, p = ?) b) None of the three will be filled incorrectly c) At least two of the three orders will be filled incorrectly? d) What are the mean and standard deviation of the binomial distribution for the number of orders filled incorrectly
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.
