If a container with nine 5-volt transistor batteries of which two are known to be defective, batteries are selected one at a time without replacement and tested until a non-defective one is found. (i) Calculate the probability that three batteries are tested. (ii) What is the probability the second selection is non defective given that the first is defective.
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.
