A student takes a 10 question, multiple-choice exam with two choices for each question and guesses on each question. Find the probability of guessing at least 6 out of 10 correctly. Assume the variable is binomial. Round the intermediate and final answers to three decimal places. P= (guessing at least 6 out of 10 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.
