The expected value of the amount of rain Saturday and Sunday are 2 inches and 3 inches, respectively. There is 50% of the chance of rain on Saturday. If it rains on Saturday, there is a 75% chance of rain on Sunday. But if it does not rain on Saturday, then there is only a 50% chance of rain on Sunday. What is the expected value(in inches) for the amount of rain over the weekend?
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.
