I love to make copies; who doesn't? There is a 75% chance that I am the first one in the copy room. If I am first, there is an 80% chance the machine works. If I am not first, there is only a 45% chance the machine works. a) What is the probability that the machine doesn't work if I am the first one in the copy room? Give your answer as a decimal between 0 and 1. b) What is the probability that the machine is working when I try to make copies? (regardless of if I was first or not) Give your answer as a decimal between 0 and 1.
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.
