probability analysis software for windows that provides an easy-to-use tool for using discrete and continuous distributions, handling all the probability combinations for you. features include binomial, poisson, normal, exponential, student t, chi squared, f, beta and lognormal distributions; inverses of normal, student t, chi squared, f, beta and lognormal distributions; lists of binomial coefficients and permutations plus more.

surface modeler is intended for modeling curves and surfaces of the high order of continuity with smooth change of curvature. with surface modeler you’ll be able to create first-class objects with curvilinear surfaces. their quality is dependent on their geometric characteristics. surface modeler is the tool of choice for modeling car surfaces, external contours of airplanes and ships, working surfaces of blades of compressor rotors.
