A class is made up of 5 boys and 10 girls Half of the girls

A class is made up of 5 boys and 10 girls. Half of the girls wear glasses. A student is selected at random from the class. What is the probability that the student is a girl with glasses? Write your answer as a fraction in simplest form.

Solution

Total number of students = 5 + 10 = 15

Number of girls =10

Number of girls who wear glasses = Half of 10 = 5

So, required probability = (Number of girls who wear glasses)/(Total number of students) = 5/15 = 1/3.

So the answer is 1/3.
