In a former assignment we calculated the winnings of a game of throwing dice. The rules were:

• Three dice are thrown.

• If the three scores are equal, the player wins €1000.

• If the three scores are consecutive, the player wins €500.

• If only two of three scores are equal, the player wins €100.

The order in which the dice are thrown is unimportant. To play a game, the player must pay €6.5.
