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.

What are the odds of rolling 3 die whose sum is 12?
Given information-
We have given 3 die whose sum is 12.
To get the sum of 12 = (4, 4, 4)
Hence, there is only 1 way out of 216 ways to succeed.
No. of ways to fail = 216-1 = 215
