Sagot :
The random variable of the number of pages in a textbook would be classified as:
### Step-by-Step Solution:
1. Identify the Type of Data:
- There are two main types of data: continuous and discrete.
- Continuous Data: Refers to data that can take any value within a given range. Examples include height, weight, and temperature. These values are often measurements and can be fractions or decimals.
- Discrete Data: Refers to data that can only take specific values. Examples include the number of students in a class, the roll of a dice, or the number of cars in a parking lot. These values are often counts and are whole numbers.
2. Consider the Nature of the Random Variable (Number of Pages in a Textbook):
- The number of pages in a textbook is a countable quantity.
- You can't have a fractional or decimal page in a textbook; pages are whole numbers.
3. Classify the Data:
- Since pages in a textbook can only be whole numbers and they are counted rather than measured, they fall under the category of discrete data.
### Conclusion:
The random variable of the number of pages in your textbook would be classified as discrete data.
