Assume that random guesses are made for thirteen multiple choice questions on a medical admissions test, so that there are n=13 trials, each with a probability of success (correct) given by p=0.20. Find the probability that the number x of correct answers is fewer than 5. The probability that the number x of correct answers is fewer than 5 is __ (round to three decimal places as needed)
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.
