Accidentally, two depleted batteries get into a set of five batteries. To remove the two depleted batteries, the batteries are tested one by one in random order. Let the random variable X denote the number of batteries that must be tested to find the two depleted batteries. What is the probability mass function of X?
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.
