We encounter probability related problems every day of our lives which include: decisions such as whether or not to trade in a specified market, which stock to invest in, the amount of money to invest in a given company etc. For this reason, probability distributions packages have been developed to enable the parties involved make better decisions thus reducing their exposure to incurring risks. In this paper, we aim at appreciating the application of packages such as mc2d, fitting of linear models and test of independence of variables in financial analysis.
