Two chess players have Elo ratings that differ by 400n, where n is a non-negative integer. How likely is the higher rated player to win for different values of n? How much more likely is the higher rated player to win than the lower rated one for different values of n? (Consider n = 0, 1, 2, . . . 4 to see a pattern or analyze the formula for win probability.)
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.
