I have an assignment image.png - Speedy Share - upload your files here which is a bit different,

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?
