A ball is drawn from a bag containing 13 red balls numbered 1–13 and 5 white balls numbered 14–18. What is the probability that (a) the ball is not even-numbered? (b) the ball is red and even-numbered? (c) the ball is red or even-numbered? (d) the ball is neither red nor even-numbered?
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.
A ball is drawn from a bag containing 13 red balls numbered 1–13 and 5 white balls numbered 14–18. What is the probability that
(a) the ball is not even-numbered?
(b) the ball is red and even-numbered?
(c) the ball is red or even-numbered?
(d) the ball is neither red nor even-numbered?
