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 boxes allow you to select a range of possible "successes," for which the applet will calculate the probability, displayed after "Selected area."

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 for situations of the general "k out of n" type, where k is the number of times a binomial outcome is observed or stipulated to occur, p is the probability that the outcome will...

This calculator computes the probability that two proportions are equal, given sample proportions. The user inputs values for x1, n1, x2, and n2. The null hypothesis is that the two proportions are equal.
