A building contractor buys 60% of his cement from supplier A and 40% from supplier B. A total of 95% of the bags from A arrive undamaged, while 75% of the bags from B arrive undamaged. Find the probability that a damaged bag is from supplier A.
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.
