Assume that in a university with 1000 students, 200 students are taking a course in mathematics, 300 are taking a course in physics, and 50 students are taking both. How many students are taking at least one of those courses? How many are taking none of those courses? How many students are taking only Mathematics?
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.
Assume that in a university with 1000 students, 200
students are taking a course in mathematics, 300 are
taking a course in physics, and 50 students are taking
both. How many students are taking at least one of those
courses? How many are taking none of those courses? How
many students are taking only Mathematics?
