Defective concrete on a construction site can be caused by either poor workmanship (selection and grading of material, pouring, curing) or poor aggregate, or both. The quality of the aggregate is affected by the quality of the workmanship, and vice versa. W = poor workmanship, A = poor aggregate On a given project: P(A) = 0.25 P(W | A ) = 0.33 P(W) = 0.45 What is the probability of at least one of the causes of defective concrete during the project to 2 decimal places?
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.
Defective concrete on a construction site can be caused by either poor workmanship (selection and grading of material, pouring, curing) or poor aggregate, or both. The quality of the aggregate is affected by the quality of the workmanship, and vice versa.
W = poor workmanship, A = poor aggregate
On a given project:
P(A) = 0.25
P(W | A ) = 0.33
P(W) = 0.45
What is the probability of at least one of the causes of defective concrete during the project to 2 decimal places?
