Of the 8000 students in Hunter College, 5000 takes statistics, 2600 takes chemistry, and 800 takes both. Suppose a random student is selected. What is the probability that he/she a) Takes neither? b) Takes statistics but not chemistry
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.
