Suppose Jon is taking a test with 10 true-false questions and 5 multiple choice questions with 4 choices each. He knows nothing, so he will answer randomly. (a) Find the expected number of true-false questions he will answer correctly. (b) Find the expected number of multiple choice questions he will answer correctly. (c) Find the expected number of total number of questions he will answer correctly. (d) Find the probability Jon answers exactly 4 questions correctly.
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.
