Well, it would certainly be a sensible question to ask why a normal distribution is a good approximation for a binomial distribution for large N. The answer is probably going to come in the form of some algebra, which will follow again from a series of assumptions (I seem to recall that you need larger sample sizes for more skewed binomial distributions).
