Mr. Rosart selects two students from his class to present their book reports. He places the names of each student in a box and randomly picks one at a time. The class has 14 boys and 12 girls. What is the probability that the second name Mr. Rosart picks is a boy, if the first one is a boy also?

Pr(2B:1b)= 13/(13+12)=13/25
