An unprepared student must take a 5-question multiple-choice test that has 5 possible answers per question. If the student can eliminate one of the possible answers on the first three questions, and if she guesses on every question, what is the probability that the following will occur? (Enter your probabilities as fractions.) (a) she will answer every question correctly (b) she will answer every question incorrectly (c) she will answer at least one question 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.
