Answer 2

Calculation of Probability

To calculate the probability of selecting a boy as the representative from the class, we need to determine the total number of students in the class and the number of boys in the class.

Given that there are 14 girls and 11 boys in the class, the total number of students in the class is 14 + 11 = 25.

The probability of selecting a boy as the representative can be calculated by dividing the number of boys by the total number of students in the class:

Probability of selecting a boy = Number of boys / Total number of students

Let's calculate the probability:

Number of boys = 11 Total number of students = 14 + 11 = 25

Probability of selecting a boy = 11 / 25

Therefore, the probability of selecting a boy as the representative from the class is 11/25.
