Rolling Dice: Sum of Points

This is a Shiny app that generates empirical histograms when simulating rolling dice and finding the total number of spots.

Motivation

The goal is to provide a visual display similar to the empirical and probability histograms shown in page 311 of "Statistics", chapter 18.

Reference: "Statistics" by David Freedman, Robert Pisani and Roger Purves (2007). Fourth Edition. Norton & Company.

Data

The data simulates rolling (by default) a pair of dice (but the user can choose between one and 10 dices). The input parameters are the number of dice, the random seed, and the number of repetitions.

Plots

There are two tabs:

1. An empirical histogram.
2. A probability histogram (probability distribution).
