For example, 3d6+4 instructs the player to roll three six-sided dice, calculate the total, and add four to it.

Different pigments can be added to the dice to make them opaque or transparent, or multiple pigments may be added to make the dice speckled or marbled. In total, there are 20 good outcomes in 1,000 possibilities, so the final probability is: P(X ≥ 27) = 20 / 1,000 = 0. In geometry, a pentagonal trapezohedron or deltohedron is the third in an infinite series of face-transitive polyhedra which are dual polyhedra to the antiprisms.

The most common physical dice have 4, 6, 8, 10, 12, and 20 faces respectively, with 6-faced die comprising the majority of dice. One typical contemporary dice game is craps, where two dice are thrown simultaneously and wagers are made on the total value of the two dice.

For instance, 10-sided dice can be rolled in pairs to produce a uniform distribution of random percentages, and summing the values of multiple dice will produce approximations to normal distributions.

Although gambling was illegal, many Romans were passionate gamblers who enjoyed dicing, which was known as aleam ludere ("to play at dice").

Using these dice in various ways, games can closely approximate a variety of probability distributions. Alternative names for dice include 'casting lots' (used in the Bible) and 'knucklebones', a game of skill played in Ancient Greece. Some dice, such as those with 10 sides, are usually numbered sequentially beginning with 0, in which case the opposite faces will add to one less than the number of faces. Similarly, pyritohedra and tetartoids are less symmetrical but still face-transitive dodecahedra: 12 sides.
