Answer
What is the probability of the winner not in homeroom b
Answered by GPT 3.5
There are a total of 43 students participating in the activities fair (8+10+7+9+10+9=43).
The probability of the winner being a 7th grader in homeroom c is calculated by taking the number of students in that specific homeroom and dividing it by the total number of students participating in the fair, which is 7/43.
Therefore, the probability of the winner being a 7th grader in homeroom c is approximately 0.163 or 16.3%.

Answered by GPT 3.5
To find the probability of the winner not being in homeroom b, we need to calculate the total number of students in homeroom b and then subtract that from the total number of students participating in the activities fair.

Total number of students in homeroom b = 10
Total number of students participating in the fair = 43

Number of students not in homeroom b = Total number of students - Number of students in homeroom b
Number of students not in homeroom b = 43 - 10 = 33

Therefore, the probability of the winner not being in homeroom b is 33/43.
