I have an assignment http://www20.speedys...nload/image.png 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?

You can approximate by the normal distribution using the mean and variance of the binomial.

Any of various mathematics software (Mathematica, MathCAD, etc.) or even most programming languages (C, Fortran, Python, R) can compute this using the exact definition of the binomial distribution. In fact, I suspect that this is the point of the problem -- not to check the student's 'look something up in a table' skills, but the check the student's ability to used some slightly more advanced computation tools.

I agree it is very wierd since we can not answer like this on an exam, but the assignment says look up in Matematics Handbook Beta.

How do you do this?

mean = np = 100x.7 = 70 , variance = np(1-p) = 100x.7x.3 = 21.

Can you handle a normal distribution with these parameters?
