General Random Variables Use MATLAB to plot the probability mass function (pmf) and the cumulative distribution function (cdf) for the sum of the roll of two. 3- sided dice minus the roll of a third. The plots are to be generated using experimental "modeling" (stochastic modeling, not deterministic formulae) for the definition of the random variable. X. As an example of the expected results, the "stem" and "stair" plots for a typical random variable analysis are shown at the right below
