The probability the winner is a 7th grader in Homeroom C can be calculated by dividing the number of 7th graders in Homeroom C who engaged in the activities by the total number of students who engaged in the activities.
From the table, we see that there are 7 students in 7th grade Homeroom C who participated in the activities.
Total number of students who participated = 7 (7th grade Homeroom C) + 5 (8th grade Homeroom C) = 12
Therefore, the probability is 7/12, which simplifies to 7/12 or 583 over 1009.
