A canoe club sponsor has taken canoeing groups through a particularly rough section of white water on a mountain river. Past trips and experience of the sponsor lead her to believe that 51% of the canoeists who attempt to paddle their way through this section will overturn. At the present time, there are 8 canoes approaching this treacherous section. Assume that the sponsor's estimate of the probability of a canoe overturning in this section of water is accurate. What is the standard deviation of the number of canoes that will capsize?
