Lisa has two choices of route when she goes to school. Route A always takes 15 minutes. Route B takes 12 minutes, unless there is a traffic jam, in which case that route will take 20 minutes. If the chance of a traffic jam is 15%, which route should she take?
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.
