It seems like you haven't provided the table with the number of students. However, I can guide you on how to solve each part of the question if you can provide the data.

  1. How many students are entered for the raffle?

    • You would need to sum the number of students from each grade and homeroom who actively participated in the engagement activities.

  2. How many students are in 7th Grade and in Homeroom C?

    • You would find the specific count of students from Homeroom C who are in the 7th grade.

  3. What is the probability the winner is a 7th grader in Homeroom C?

    • This probability can be calculated using the formula:
      \[ \text{Probability} = \frac{\text{Number of 7th graders in Homeroom C}}{\text{Total number of students entered for the raffle}} \]

  4. What is the probability the winner is NOT in Homeroom B?

    • To find this, you can calculate the number of students not in Homeroom B and then use the formula:
      \[ \text{Probability} = 1 - \frac{\text{Number of students in Homeroom B}}{\text{Total number of students entered for the raffle}} \]

Once you provide the student counts from the table, I can help you with the exact numerical answers.
