This author's understanding of statistics needs to be improved. "Imagine your daughter and her seven friends came over and you knew that one of them would definitely be pregnant. If your daughter went to Robeson High School in Chicago, this would be the case." A randomly selected group of 8 girls from this school would yield a lack of pregnancies ~29% of the time. Granted, friend groups will probably not be random, but I think this would increase the chance of pregnant girls clustering together and therefore producing most friend-groups with no pregnancies.
