To determine the number of trout in a lake, a conservationist catches 200 trout, tags them and throws them back into the lake. Later, 36 trout are caught; 12 of them are tagged. How many trout would the conservationist expect to be in the lake?
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.
