Five individuals from an animal population thought to be near extinction in a certain region have been caught, tagged, and released to mix into the population. After they `have had an opportunity to mix, a random sample of 10 of these animals is selected. Let X= the number of tagged animals in the second sample. If there are actually 25 animals of this type in the region, what is the probability that (a) X - 2? (b) X is less than or equal to 2? (c.) What is the mean and variance of the hypergeometric

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.
