In the calculator, probability distributions as normal distribution, t distribution, F distribution, chi--square distribution, Weibull distribution, lognormal distribution, binomial distribution, Poission distribution, negative binomial distribution, and uniform distribution, etc., were available for use. Probability density function, cumulative distribution function, and inverse cumulative distribution function of these probability distributions can be calculated. The calculator was developed as a standalone software using Matlab. Full codes and software were provided. http://www.iaees.org/publications/journals/selforganizology/articles/2025-12(3-4)/probTable.pdf
