WebApr 3, 2024 · I googled and found that if n approaches infinity and p and q are large (not close to either 1 or 0) then it follows a normal distribution. But if p is large np should also be infinite. So it seems to me that normal distribution can only approximate the binomial distribution when n, p, and q all are finite.
