A Finance professor created a multiple-choice examination with 100 questions for his students. Each question has five possible answers. Assume that a student who has done the homework and attended lectures has an 85% probability of answering any question correctly. a. If a student does not pass the examination but the student answers 28 or more questions correctly, the student can appeal to take another new examination. If pass, the highest grade can only be a passing grade, say D. Assume that a student has not attended class and has not done the homework for the course. Furthermore, assume that the student will simply guess at the answer to each question. What is the probability that this student will answer 28 or more questions correctly and have an opportunity to appeal to take another new examination?
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.
