n an assessment of the quality of computer software, the number of errors per 1,000 lines of computer code is described as a Poisson distribution with an average of 5 errors per 1,000 lines of code. X~Poisson(5). Find the probability that in the next 1000 lines of code examined exactly 4 errors will be found, P(X=4). (Correct to three 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.
