In a computer laboratory, the teacher wants to find out if there is a defective computer. Supposed three computers were tested at random, she asks one of her Computer System Servicing students to list all the possible outcomes, such that D represents the defective computer and N represents the non-defective computer. Let X be the random variable for the number of defective computers. Then, illustrate the probability distribution of the random variable 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.
