A breath analyzer is a device used by the police to test whether drivers exceed the legal limit set for the blood alcohol percentage while driving. Let A denote the event "breath analyzer indicates that legal limit is exceeded" and B denote the event "driver's blood alcohol percentage exceeds legal imit". Describe in words the meaning of P(A|B).
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.
Here we have two events A and B. The event A here denotes that the legal limit is exceeded and the event B denotes that the blood alcohol percentage exceeds legal limit.
