In exercises 15-20, assume that random guesses are made for eight multiple choices questions on an SAT test, so that there are n=8 trails, each with probability of success (correct) given by p= 0.20. Find the indicated probability for the number of the correct answer. problem number 18 is; Find the probability that the number X of correct answers is no more than 2.
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.
