A bag contains a total of 9 marbles of which 6 are red and 3 are blue. You draw 3 marbles with replacement. a) Find the probability that all three marbles are blue. b) Define the following events: X: you get at least one red marble Y: you get at least one blue marble Find the conditional probability P(Y|X)
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.
