A jar contains 5 fair coins and 7 biased coins. Each biased coin is three times as likely to show Heads as Tails, when it is tossed. A coin is randomly selected from the jar and tossed. The outcome is observed to be Tails. What is the probability that the coin selected is a fair coin?
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.
