To find the probability that a girl will be the line leader, we need to determine the total number of possible outcomes and the number of favorable outcomes.
Total number of possible outcomes = Total number of students = 13 boys + 17 girls = 30 students
Number of favorable outcomes = Number of girls = 17 girls
Probability = Number of favorable outcomes / Total number of possible outcomes
Therefore, the probability that a girl will be the line leader is 17/30.
To find the probability of a girl being the line leader, we need to determine the total number of students and the number of girls in the class.
Given that there are 13 boys and 17 girls in the seventh-grade class, the total number of students is 13 + 17 = 30.
To find the probability of a girl being the line leader, we divide the number of girls by the total number of students:
Probability = Number of girls / Total number of students = 17 / 30.
Therefore, the probability of a girl being the line leader is 17/30.
