I could find out all this info on my calculator with bionompdf/bionomcdf. The slider that the previous version of this site had may have helped up the usefulness.

[6]  2014/05/26 22:49   Female / 40 years old level / A teacher / A researcher / Very /
Purpose of use
To demonstrate to my class that a normal curve can be used to approximate a binomial distribution and that as n gets larger the approximation gets better
Comment/Request
It would be even better if there was a way to superimpose the normal curve onto the histogram
