John has 2 coins, one fair and the other unbalanced so that the probability of its coming up tails is 2/3. He picks one of the coins at random, tosses it, and it comes up tails. What is the probability that he picked the unbalanced coin? (Enter your probability as a fraction.)
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.
