To calculate the probability that a randomly selected student is in 9th grade and chose pizza, you need two key pieces of information:

  1. The total number of students surveyed.
  2. The number of students who are in 9th grade and chose pizza.

From the data provided, we notice that there is a total count (which might represent the total number of students surveyed).

However, the specific breakdown of students who chose pizza is not provided.

If we assume that the total number of students from the total row (which appears to be 134) represents the total surveyed, and if we denote the number of students who are in 9th grade and chose pizza as \(N_{9th, pizza}\):

The formula for the probability \(P\) that a randomly selected student is in 9th grade and chose pizza is:

\[ P(9th \text{ grade and pizza}) = \frac{N_{9th, pizza}}{Total} \]

To provide a numerical answer, we would need the value of \(N_{9th, pizza}\). If you have that number, you can substitute it into the formula to get the probability.

Without that specific number, we cannot calculate the exact probability. Please provide additional details or the number of 9th graders who chose pizza in order to proceed with the calculation.
