This Binomial applet allows the user to adjust the n and the p and see the resulting histogram. There is also an option to overlay the normal distribution over the histogram. The "area from" and "to" scrollbars and text...

The page will calculate the following: exact binomial probabilities, approximation via the normal distribution, approximation via the poisson distribution. This page will calculate and/or estimate binomial probabilities...

This article, created by authors B.C. Lyon and M.W. Maxfield of Louisiana Tech University, describes a hands-on class activity for understanding the bivariate normal distribution by constructing a three-dimensional...
