The pool of students in a calculus class consist of 22 sophomore and 8 freshmen. If seven students are to be selected at random from the class, (c) how many different groups of seven students consist entirely of sophomore? (d) what is the probability that the group will consist entirely of freshmen? (Leave as a fraction)
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.
