When a value is randomly selected from a finite categorical population, each population member is equally likely to be selected. However some values usually appear several times in the population, so the probability of any particular category equals the proportion of population values that are that category.
The population below is categorical and a bar chart summarises the values. The number of values in category is shown, making it easier to calculate the required probability exactly (using the template provided).
Repeat with a few other questions.
