A surgery has a success rate of 75%. Suppose that the surgery is performed on three patients. What is the probability that the surgery is successful on at least 2 patients? On average, how many surgeries can we expect to be successful if performed on a group of three patients? What is the standard deviation of the number of successful surgeries performed on a group of three patients?
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.
