As the name suggests, "Probability Calculator" is an easy-to-use probability calculator. Using it you can easily pick one of 40 different probability distributions, calculate, plot and manipulate it's:

* probability density function (pdf),
* cumulative density function (cdf),
* survival function,
* hazard function,
* cumulative hazard function

For each distribution, a point percent function (ppf) for arbitrary probability (p) can also be calculated. In addition, distribution first four moment estimates are also calculated (mean, variance, skewness, and kurtosis).

All results are presented in graphical (distribution function plot) or textual (tabulated data) form. Textual results can be exported to several formats, including text, xml, html table or copied to clipboard. Graphical results (distribution plot) can be exported to pdf, eps, emf, jpeg, gif or xaml. Registered version also offers full control over plot appearance with several built-in templates. If templates are not enough, user can still control and change virtually any property of plot.

To resume: Probability Calculator is a simple, yet effective tool which can be used by students, scientists, teachers or professional analysts alike.
