A fire alarm in a school has two independent circuits. The alarm will function if one or both of the circuits are working. If the probability that the first circuit is working is 0.91, and the probability that the second circuit is working is 0.90, what is the probability that the fire alarm will function? The probability is 0.82

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.
