Math class has 6 girls and 2 boys in the seventh grade and 3 girls and five boys in the right grade. the teacher randomly selects a 7th and a 8th grader. What is the probability that the student she selects are both girls

The Probability that the 7th grader is a boy = number of boys / (total kids) = 4 / (4+4) = 1/2 the Probability that the 8th grader is a boy = 5 / (5+7) = 5/12 the Probability that both are boys = 1/2 * (5/12) = 5/24 or 20.8percent
