PD.com: "a rather irritating form of hermetic terrorism".

Yeah, like I said, the probability he'll be right is 66%.But the probability his predictions will have any effect on his final score seems to be 50%.The only time a prediction can be considered "wrong" is if he says rolls of 1&2 are "High", and rolls of 5&6 are "low".That really seems to me to be a more elaborate way of calling heads and tails.

If you want to PM them to me, I can add it to the spreadsheet.

For example, I could roll the die, and ask, "is it 1&2, or is it 5&6?", and simply re-roll if it's 3&4, because either answer would be correct.So, with a randomized rolling process, it should come up 1&2 equally as often as 5&6. That's 50%, right?
