**Title: Understanding Uniform Probability Distribution**

The random-number generator on calculators randomly generates a number between 0 and 1. The random variable \(X\), the number generated, follows a uniform probability distribution.

1. **Identify the Graph of the Uniform Density Function:**
   - Choose the correct graph of the uniform density function from the options below:

     **A.**, **B.**, **C.**

   Analyze the visual representation of each graph. The correct graph for a uniform distribution between 0 and 1 is a horizontal line representing constant probability within the range, over an interval on the x-axis from 0 to 1, with a height of 1 to cover an area of 1.

2. **Probability Calculations:**

   - **(b) What is the probability of generating a number between 0.56 and 0.97?**
     - Calculate and simplify your answer by finding the difference between 0.97 and 0.56, since it is a uniform distribution.

   - **(c) What is the probability of generating a number greater than 0.84?**
     - Calculate and simplify your answer by subtracting 0.84 from 1, representing the upper limit of the distribution.

**Graphs Explanation:**

- Each graph depicts a rectangle with the x-axis labeled from 0 to 1.2.
- The y-axis is labeled "Density" from 0 to 1.2.

**Choices:**
- **Graph A:** Displays a horizontal line between 0 and 1 at a height of 1 on the y-axis.
- **Graph B:** Displays a horizontal line from just over 0 to 1 at a height of approximately 0.8.
- **Graph C:** Displays a horizontal line starting after 0 and ending before 1 at a lower height.

The correct representation for a uniform distribution between 0 and 1 is Graph A.
