The random variable x is known to be uniformly distributed between 1.0 and 1.5.
B. Compute P(x=1.25)
C. Compute P(1<=x<=1.25)
D. Compute P(1.2<x<1.5)

Transcribed Image Text:The random variable \( x \) is known to be uniformly distributed between 1.0 and 1.5.
**a. Which of the following graphs accurately represents this probability density function?**
1. **Graph 1:**
- The graph shows a constant horizontal line for \( f(x) = 1 \) from \( x = 0 \) to \( x = 1.5 \).
- The y-axis is labeled from 0 to 2.
- The x-axis is labeled from 0 to 2, with intervals of 0.25.
2. **Graph 2:**
- The graph shows a constant horizontal line for \( f(x) = 2 \) from \( x = 0 \) to \( x = 1.0 \).
- The y-axis is labeled from 0 to 2.
- The x-axis is labeled from 0 to 2, with intervals of 0.25.
3. **Graph 3:**
- The graph shows a constant horizontal line for \( f(x) = 2 \) from \( x = 1.0 \) to \( x = 1.5 \).
- The y-axis is labeled from 0 to 2.
- The x-axis is labeled from 0 to 2, with intervals of 0.25.
**b. Compute \( P(x = 1.25) \).** If your answer is zero enter “0” (to 1 decimal).
**c. Compute \( P(1 \leq x \leq 1.25) \) (to 2 decimals).**
**d. Compute \( P(1.2 < x < 1.5) \) (to 2 decimals).**
The correct graph selection is indicated as **Graph #3**. Inputs are provided for parts b, c, and d, where users are prompted to enter their computed probabilities.
