Two pumps connected in parallel fail independently ofone another on any given day. The probability that onlythe older pump will fail is .10, and the probability thatonly the newer pump will fail is .05. What is the probabilitythat the pumping system will fail on any given day(which happens if both pumps fail)?
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.
