A math class has girls and boys in the seventh grade and girls and boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition. What is the probability that the students she selects are both girls? Write your answer as a fraction in simplest form
I think the answer is 1/3 since on possible way is a boy to boy, boy to girl, and gurl to girl. So there are 3 ways and one of them has a chance of being a girl and a girl. So the answer would be 1/3
