Compute probabilities, determine percentiles, and plot the probability density function for the normal (Gaussian), t, chi-square, F, exponential, gamma, beta, log-normal, Pareto, and Weibull distributions. Compute probabilities, approximate percentiles, and plot the probability mass function for the binomial, geometric, hypergeometric, Poisson, and negative binomial distributions.
