For the binomial distribution with the given values for n and p, state whether or not it is suitable to use the normal distribution as an approximation.

f n is large enough, B(n, p) is given by the normal distribution.

A basic approximation can be improved in a simple way by using a suitable continuity correlation. The basic approximation generally improves as n increases (at least 20) and is better when p is not near to 0 or 1. Various rule of thumb may be used to decide whether n is large enough, and p is far enough from the extremes of zero or one:

N(NP,nP) (1-P) if n is higher than p then the skew of the distribution is not too great. its therefore possible to use normal disribution.
