**Identifying Random Variables: Discrete vs. Continuous***Question:*Identify the given random variable as being discrete or continuous.*Scenario:*The height of a randomly selected student.*Options:*- Discrete (Radio button option, not selected)- Continuous (Radio button option, selected with an "X" mark)In this educational exercise, you are asked to categorize the random variable—specifically, the height of a randomly selected student—into one of two types: discrete or continuous. A discrete variable can only take on a finite number of values, whereas a continuous variable can take on an infinite number of values within a given range. Here, the height is marked as continuous.
