Compute probabilities a n d plot the probability mass function for the binomial, geometric, Poisson, hypergeometric, a n d negative binomial distributions. Compute probabilities, determine percentiles, a n d plot the probability density function for the normal (Gaussian), t, chi-square, F, exponential, gamma, beta, a n d 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.
