A secondary school is offering two extracurricular classes, one in Photography and the other in Swimming. These classes are open to all of the 250 students in the school. Suppose there are 48 students in the Photography class, 34 in the Swimming class, and 12 who are in both classes. If a student is randomly chosen, what is the probability that this student is not enrolled in any one of these 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.
