A company has 10 delivery trucks, 6 of which are due in for an inspection. Suppose 3 of these 10 trucks are selected at random. a) What is the probability that at least 2 of the selected trucks will be due for inspection? b) What is the expected value of the number of selected trucks that will be due for inspection, rounded to two 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.
