You should still assume that no refrigerator has both too much and too little enamel; however, use the table below instead of that given in your book to answer the following questions. Event Probability Too much enamel 0.18 Too little enamel 0.2 Uneven application 0.28 No defects noted 0.52 (1) What is the probability of a paint defect?
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.
You should still assume that no refrigerator has both too much and too little enamel; however, use the table below instead of that given in your book to answer the following questions.
| Too much enamel | 0.18 |
| Too little enamel | 0.2 |
| Uneven application | 0.28 |
| No defects noted | 0.52 |
(1) What is the probability of a paint defect?
(2) What is the probability of a paint defect which includes an improper amount of paint?
(3) What is the probability of a paint defect which results from an improper amount of paint and uneven application?
(4) What is the probability of a paint defect which results from the proper amount of paint, but uneven application?
