Probability = number of positive outcomes / number of possible outcomes

Probability that a student in grade 9 is in favor of extending the school day =

number of students in 9 grade in favor / number of students in grade 9

number of students in 9 grade in favor = 5

number of students in 9 grade = 5 + 3 + 9 = 17

Probability = 5 / 17

Answer: 5 / 17
