A bag contains ten pencils. Three of the pencils are red, and the rest are brown. If two pencils are drawn successively at random and without replacement, find the following four probabilities: a) The first pencil-drawn is red and the second pencil-drawn is brown; b) Both pencils are red; c) One pencil is red and the other is brown (the order in which they are drawn doesn't matter); d) If the second pencil-drawn is red, what is the probability that the first pencil-drawn was
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.
