Let's consider two box containing blue and red balls.While box 1 has 3 red and 2 blue balls.Box 2 has 2 red and 8 blue balls. A fair coin is tossed and one of the boxes is selected depending on result of coin.If result is Tails,Box 1 is selected.When the result is Head,Box 2 is chosen. I know that ı have chosen red ball.What is the probability that it was drawn from the Box 1 ?

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.
