A drug company wants to investigate whether people feel more energised if they take vitamin supplements. Each week each person categorises their energy level as one of High, Medium and Low, and they also record whether they took the supplements that week. The results for one person are as follows: Performance High Medium Low Yes 14 Supplements? No 7 4 5 (a) Calculate the row and column totals. (b) Calculate the joint and marginal probability distributions. (c) Calculate the conditional probability distribution for the person's performance for the weeks when they took the supplements.

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.
