Expert Solution
Step 1

There are two types of variables: Continuous variables and discrete variables.

Continuous variables can take any value within the range (no specified count), whereas discrete variables take a finite number of values. For example, the number obtained on a die is a discrete variable as it takes only the values 1, 2, 3, 4, 5, and 6, while the amount of claim can take any values with no specified count, so it is a continuous random variable.
