A test consisting of 25 multiple choice questions with 5 answer choices for each question is administered. For each question, there is only one correct answer. (a) Let X be the number of correct answers if a student guesses randomly from the five choices for each of the 25 questions. What is the probability distribution of X?
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.
