Description

The experiment consists of rolling \(n\) dice, each governed by the same probability distribution. The die distribution can be chosen from the selection box; the options are:

• fair: each face has probability \(\frac{1}{6}\).
• 1-6 flat: faces 1 and 6 have probability \(\frac{1}{4}\) each; faces 2, 3, 4, and 5 have probability \(\frac{1}{8}\) each.
• 2-5 flat: faces 2 and 5 have probability \(\frac{1}{4}\) each; faces 1, 3, 4, and 6 have probability \(\frac{1}{8}\) each.
• 3-4 flat: faces 3 and 4 have probability \(\frac{1}{4}\) each; faces 1, 2, 5, and 6 have probability \(\frac{1}{8}\) each.
• skewed left: face \(i\) has probability \(\frac{i}{21}\) for \(i \in \{1, 2, 3, 4, 5, 6\}\).
• right right: face \(i\) has probability \(\frac{7 - i}{21}\) for \(i \in \{1, 2, 3, 4, 5, 6\}\).

Random variable \(X_i\) gives the score on die \(i\) and is recorded on each update. These variables form a random sample of size \(n\) from the die distribution. The number of dice \(n\) can be varied from 1 to 56 with the scroll bar.
