Corporations such as banks, where a computer is essential to day-to-day operations, often have a second, backup computer in case of failure by the main computer. Suppose that there is a 0.002 chance that the main computer will fail in a given period and a 0.008 chance that the backup computer will fail while the main computer is being repaired. Suppose these failures represent independent events, and find the fraction of the time the corporation can assume that it will have computer service. How realistic is our assumption of independence? The assumption of independence isrealistic. (Round to six 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.

Question
Transcribed Image Text:Corporations such as banks, where a computer is essential to day-to-day operations, often have a second, backup computer in case of failure by the main computer. Suppose
that there is a 0.002 chance that the main computer will fail in a given period and a 0.008 chance that the backup computer will fail while the main computer is being repaired.
Suppose these failures represent independent events, and find the fraction of the time the corporation can assume that it will have computer service. How realistic is our
assumption of independence?
The assumption of independence is realistic.
