Rework problem 11 from section 3.4 of your text, involving the flipping of either a fair or weighted coin. Assume that the weighted coin yields a heads with probability 0.8. You select one of the two coins at random, and flip it 2 times, noting heads or tails with each flip. What is the probability that the weighted coin was selected, given that all 2 flips turned up heads?
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.
