A multiple choice question has c available choices. Let p be the probability that the student knows the right answer, and 1−p that he does not. When he does not know, he chooses an answer at random. Given that the answer the student chooses is correct, what is the probability that the student knew the correct answer?
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.
