A class is made up of 6 boys and 12 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?
1/2 of 6 is 3. So we want the probability we pick any of the 3 girls wearing glasses.
We have a total of 6 + 12 = 18 people.
Our probability is 3/18, or 1/6.
