Suppose that the true knowledge level of a student taking a test is 67%. This means that if a student is presented with a randomly selected question about the material, there is a 67% chance that he/she will give the correct answer. This student takes a test consisting of 15 randomly selected questions. What is the probability that he/she will get 12 or more answers correct? (Provide your answer as a number between 0 and 1, rounded to 3 decimal places.)
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.
