To find the probability that a randomly selected student is in 9th grade and chose pizza, we will use the information in the table.

  1. The number of 9th graders who chose pizza is 30.
  2. The total number of students surveyed is 450.

The probability can be calculated using the formula:

\[ P(\text{9th grade and chose pizza}) = \frac{\text{Number of 9th graders who chose pizza}}{\text{Total number of students}} = \frac{30}{450} \]

Calculating this gives:

\[ P(\text{9th grade and chose pizza}) = \frac{30}{450} = \frac{1}{15} \approx 0.0667 \text{ or } 6.67% \]

Therefore, rounding to the nearest whole percentage, the correct answer is:

7%

So the answer is 7%.
