Question

A science class has 5 girls and 5 boys in the seventh grade and 5 girls and 3 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?

Answer 1

These are two independent selections, so the probability is the P(A) * P(B)

Probability of A = (5/10) = .50 and probability of B = (5/8) = .625 So final probability is .50*.625 = .3125 or 31.25%
