Answer:

The probability of an eighth grader winning is 1/3

Step-by-step explanation:

Total no. of students = 42

Number of students in 7th grade = 21

Number of students in 8th grade = 14

Number of students in 9th grade = 7

Probability of event = \frac{\text{Favorable outcomes}}{\text{Total outcomes}}

So,the probability of an eighth grader winning= \frac{14}{42}=\frac{2}{6}=\frac{1}{3}

Hence The probability of an eighth grader winning is 1/3
