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.
4: A firm employs 500 workers, 120 of whom have a lower level of education (L),
180 have an intermediate (I) and 200 have a high level of education (H). In one

following table shows the joint
i. Which of the three age groups are most likely to receive performance pay
and which are least likely to receive performance pay?
