Probability Distributions
Free AppAbout Probability Distributions
Compute probabilities and plot the probability mass function for the binomial, geometric, Poisson, hypergeometric, and negative binomial distributions. Compute probabilities, determine percentiles, and plot the probability density function for the normal (Gaussian), t, chi-square, F, exponential, gamma, beta, and log-normal distributions.
Some knowledge of probability distributions is required! If you don't know what a "binomial" distribution is, for example, this application will not be useful to you.

This is the only probability calculator I've found that has a normal distribution calculator with the necessary amount of precision required for my actuary exams! It can calculate normal and inverse normal, a feature which I've also not been able to find elsewhere. Bonus points for including graphs and formulas for all the distributions available! Graphics are nice and layout is intuitive. No complaints here! Very well done :-)

No strange access needed. Free, and much easier to use than Excel. It's been a boon for my stats classes to the point where I've recommended it to other students.
