Sums of Discrete Random Variables

1. [Exercise 5.2.2] Let [Maple Math] , [Maple Math] , ..., [Maple Math] denote the outcomes when rolling n fair dice. Let [Maple Math] + ... + [Maple Math] equal the sum of these n rolls. Use animation to plot probability histograms for the distribution of [Maple Math] . Solution

2. [Exercise 5.5.11] Let [Maple Math] , [Maple Math] , ..., [Maple Math] denote the outcomes when rolling n fair m -sided dice. Let [Maple Math] + ... + [Maple Math] equal the sum of these n rolls. Use animation to plot probability histograms for the distribution of [Maple Math] . Superimpose an approximating normal p.d.f. Solution
