Of the 120 pharmacy freshman, 65 are taking mat-150 and 47 taking physics 20 students of the freshman are not enrolled in either class a) how many students are enrolled in both classes b) what is the probability that a freshman selected at random enrolled in both classes
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.
Given that
Total number of freshman is 120.
There are 65 freshman taking mat-150 and 47 taking physics and 20 students of the freshman are not enrolled in either class.
