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.

The assignment does not say so it does not matter.

Hi;

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

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?
