A lot of 50 circuit boards contains 5 defective ones. Suppose 10 of these circuit boards are selected for inspection. After they have been inspected, all of the non-defective selections are returned to the lot, and all of the defective selections are replaced with good ones. What is the expected value of the number of defective circuit boards that will remain in the lot after this inspection/replacement process has been performed once?
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.
