Yes. The figure of 99.58% given by Charles Frey is correct. More precisely, it's about 99.5815978%. Doug McLaren's figure of 51% for nine people is also off. The correct figure is about 53.4504048%. The answer of nine people is correct though, since the probability for eight people is about 44.5838152%.
