DiceLottery

logo DiceLottery is a program which maps (random) events from an available source to a desired destination. For instance you can choose lottery numbers to bet on by throwing a pair of dice (several times). This way, you can use an available, fair source of events which you trust (e.g. a coin, a pair of dice) and map its outcomes to your desired destination (e.g. lottery numbers, the winner for a drawing).

The program also ensures fairness in the mapping it performs (your source of events must also be fair of course). For instance when throwing a coin 3 times in order to choose a day of the week, the mapping is performed from 8 (=23) to 7 events. If all 8 would be mapped, then the 7 days of the week would not have equal probabilities (and thus the mapping would not be fair). The program will only map (the first) 7 inputs and report that the mapping can't be performed if you enter the 8th one.
