The total number of students who participated in the engagement activities is 8 + 10 + 7 + 9 + 10 + 9 = 53.
The probability that the winner is a 7th grader in Homeroom C is the number of 7th graders in Homeroom C who participated divided by the total number of students who participated, which is 7 / 53 = 0.1321 or 13.21%.
Therefore, the probability that the winner is a 7th grader in Homeroom C is 13.21%.

as a fraction?
The probability that the winner is a 7th grader in Homeroom C as a fraction is 7/53.
What is the probability the winner is NOT in Homeroom B?
To find the probability that the winner is NOT in Homeroom B, we need to find the total number of students who are not in Homeroom B and divide it by the total number of students who participated.
The number of students who are not in Homeroom B is 8 + 7 + 9 + 9 = 33.
The total number of students who participated is 53.
So, the probability that the winner is NOT in Homeroom B is 33/53 or approximately 0.6226 or 62.26%.
The number of students who are not in Homeroom B is 8 + 7 + 9 + 9 = 33.
The total number of students who participated is 53.
So, the probability that the winner is NOT in Homeroom B is 33/53 or approximately 0.6226 or 62.26%.
