### Normal Distribution and Probability

A normal distribution has a mean of 32 and a standard deviation of 6. Find the probability that a randomly selected x-value from the distribution is in the given interval.

#### Graphs Explanation:

1. **First Graph:**
   - **Horizontal Axis (x):** The x-axis represents the values of the random variable x, ranging from 8 to 56.
   - **Shaded Area (Blue):** The portion of the graph shaded in blue represents the interval from 26 to 38. This means we are looking for the probability that x is between 26 and 38.
   - **Distribution Curve:** The curve is a normal distribution centered at the mean value of 32, with a standard deviation of 6.

   **Probability Calculation:**
   - Insert the calculated probability percentage in the box provided.

2. **Second Graph:**
   - **Horizontal Axis (x):** Similar to the first graph, the x-axis ranges from 8 to 56.
   - **Shaded Area (Blue):** The shaded region represents the interval from 20 to 32. Here, we seek the probability that x is between 20 and 32.
   - **Distribution Curve:** Again, it's a normal distribution with mean 32 and a standard deviation of 6.

   **Probability Calculation:**
   - Insert the calculated probability percentage in the box provided.

### Summary
These graphs provide visualizations for finding the probability that a randomly selected x-value falls within specified intervals of a normal distribution. You can compute these probabilities using statistical tools or z-tables for normal distributions.
