any help is appreciated!! 

The time (in minutes) until the next bus departs a major bus depot follows a distribution with \( f(x) = \frac{1}{20} \) where \( x \) goes from 25 to 45 minutes.

**Part (a)**

**Part (b)**

Give the distribution of \( X \). (Enter exact numbers as integers, fractions, or decimals.)

\( X \sim \) (________, ________)

**Part (c)**

Graph the probability distribution.

There are four graphs displayed, each representing different probability distributions. The correct graph should represent a uniform distribution with a constant probability \( f(x) = \frac{1}{20} \) over the interval from 25 to 45 minutes.

1. **First Graph:** 
   - Horizontal line at \( f(x) = 0.05 \) from \( x = 0 \) to \( x = 50 \).

2. **Second Graph:** 
   - Horizontal line from \( x = 25 \) to \( x = 45 \), with a height of \( f(x) = 0.05 \).

3. **Third Graph:** 
   - Horizontal line at \( f(x) = 0.20 \) from \( x = 0 \) to \( x = 50 \).

4. **Fourth Graph:** 
   - Horizontal line from \( x = 5 \) to \( x = 15 \), with a height of \( f(x) = 0.05 \).

The correct graph should be the second one, representing the uniform distribution over the interval from 25 to 45.
