A bag contains 4 red marbles and 5 blue marbles. 1. If 3 marbles are randomly selected from the bag (without replacement),find the probability that exactly one of the three marbles selected is red? Expressyour answer as a reduced fraction. 2.A random draw of 3 marbles from the bag is considered a success if all 3marbles have the same color. If a sequence of 3-marble draws are performed, findthe probability that the first success occurs on the 6th draw.
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.
