Description
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.
Recent changes: Enabled landscape mode. Small UI changes. Improved rendering of Formulas. Updated SDK to version 36.

Very goods app to help me calculate the chance for each distribution. It would be great if the app contains the Uniform distribution.
