Three marbles are selected at random and without replacement from an urn containing 5 black marbles and 8 green marbles. Let the random variable X denote the number of green marbles drawn. a) List the outcomes of this experiment. b) Find the value assigned to each outcome of the experiment by the random variable X. c) Find the event consisting of the outcomes of the experiment to which a value of 2 has been assigned by 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.
