To calculate the probability that a randomly selected student is in 9th grade and chose pizza, we need to find the intersection of those two events.
From the table:
- Number of 9th grade students who chose pizza = 30
- Total number of students who chose pizza = 50
- Total number of 9th grade students = 200
Probability = (Number of 9th grade students who chose pizza) / (Total number of 9th grade students)
Probability = 30/200 = 0.15 = 15%
Therefore, the probability that a randomly selected student is in 9th grade and chose pizza is 15%.
