In a given Finite class 1/2 of students are juniors, 3/8 are sophomores, and the rest are freshmen. Of those in the class, 2/7 of the juniors are business majors, 3/7 of the sophomores are business majors, and 5/7 of the freshmen are business majors. What is the probability that a randomly-selected student is a freshman given that she is not a business major?
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.
