A quiz consists of 10 multiple choices questions with five choices A, B, C, D, and E. I did not study and randomly picked one answer for each question Find the probability that * I get at least one question correct * I pass the quiz. A passing grade is 60% or better * I receive an “A” on the quiz (i.e., 90% or better). * How many questions would you expect me to get correct? * Obtain the standard deviation of the number of correct answers.
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.
