In a cement store there are 1000 bags of cement, 500 of which are salt-resistant cement, 200 of which are unsuitable for use, and half of the unsuitable for use is of the salt - resistant type .when one bag is pulled randomly from the store find: a: The probability that it is salt- resistant and unsuitable for use b: The probability that it is unsuitable for use if it is salt- resistant C: The probability of being salt- resistant if it is unsuitable for use
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.
