Twenty-sided. When it comes to games of chance that utilize die, not all rely on the 6-sided version we are most familiar with. In fact, for games such as Dungeons and Dragons, 20-sided die are used. The mean, x, of a discrete random variable can be computed by x = X[infinity] i=0 xi · p(xi) (1) where x is the set of values that the random variable can take and p(xi) is the probability of the ith element of x. For a 20-sided die, x = {1, 2, ..., 19, 20} and p(xi) = 1/20. Given this information, write a MATLAB script called twentysided. m that computes the mean value of rolling two 20-sided die (and adding the result). Compute the mean by rolling two 20-sided die 50 times. Once computed, display the answer to the command window with the message ’The mean of two 20-sided die is: x’. You can assume that both rolls are independent of one another. In addition, create a MATLAB movie plot in the same script which shows the convergence of the experimental mean to the actual mean you calculated above. Just like the movies, you can create a plot, pause for a moment, and then update the plot again to give the effect of a moving picture show. This is done by creating a loop that updates the plot and pauses a brief moment before iterating again. In order to accomplish the movie you will need to
