There are 64 employees in a certain firm. We know that 40 of these employees are male, 6 of these males are secretaries, and 18 secretaries are employed by the firm. What is the probability that an employee chosen at random is a secretary, given that the person is a female?
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.
