Two comments: (1) If the coins are numbered (on the non-zero side) 1, 2, 4, 8, ... then each possible total occurs exactly once. If Derek's coins are labelled 0 and X (X = 1, 2, 3, ...), these new coins are labelled 0 and 2^(X-1). I don't know if this observation is helpful, since I don't

This is an odd distribution... I think it may somehow be related to the binomial distribution, but I'm not certain. The idea is difficult to explain, so here's a "real-life" example of generating the distribution: I have four coins in my hand. Each coin has a number on both sides. All coins have
