Binomial distribution
I have an assignment (see picture) 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?

Re: Binomial distribution
Hi;
Which do you want a normal distribution? There are approximations for everything.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Binomial distribution
Hi;
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.
