At a local high school, 30% of the students are on a school sports team, 25% take at least one Advanced Placement (AP) class, and 10% are on a sports team and take at least one AP class. If a student was randomly selected from this school, what is the probability that the student is on a sports team or takes at least one AP class?
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.
