Help students recognize two ideas: The greater the sample size, the closer the Normal approximation is to the binomial distribution. The closer that p is to 0.5, the more symmetric the binomial distribution, and therefore closer to Normal. These two ideas are combined to form the Large counts condition np > 10 and n (1 - p) > 10.
