There are 2 coffee machines at the Café. Probability that machine1 fails is 0.3. Probability that machine2 fails is 0.3. Probability that both machine1 and machine2 fail is 0.12. What is the probability that none of machines 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.
There are 2 coffee machines at the Café.
Probability that machine2 fails is 0.3. Probability that both machine1 and
machine2 fail is 0.12. What is the probability that none of machines fail?
