B(100,.7) can be approximated by N(70,√(21)).

See this page to understand what I did and see if you will require a continuity correction which will allow more accuracy.

]]>Which do you want a normal distribution? There are approximations for everything.

]]>I have to use Mathematics Handbook for Sience and Engineering to solve the problem,

I can look it up in tables. But the tables for binomial functions is only up to 20,

Normal Distribution to 3.4 and Poisson up to 24 in some cases.

So how do I do it? Approximation of some kind?
