A thirdgrade class has 16 girls and 15 boys. A fourthgrade class has 18 boys and 15 girls. When picking teams for PE, captains will make one selection from the fourthgrade class and one selection from the thirdgrade class before the other team picks. Assuming everyone has an equally likely chance of being selected, what is the probability that the first captain will choose two boys on the first pick?
