f all the registered automobiles in Colorado, 10% fail the state emissions test. Ten automobiles are selected at random to undergo an emissions test (Round the answer to three decimal places if needed). a. Find the probability that exactly three of them fail the test. b. Find the probability that fewer than three of them fail the test. c. Find the probability that more than two of them fail the test.
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.
