That's an interesting point of view. If we know the rate of an event's outcome, in aggregate, is X, why is it important to know if A * B * C = X, or to know A/B/C at all? Totally sincere - I don't know if I'm missing something. Imagine we're bottling soda in plastic bottles. There's an X% chance that a bottle explodes during the process. We also know if we over-fill a plastic bottle with CO2 the start it makes it slightly more elastic, and empirically it reduces that rate by Y%. We're not really sure why they were exploding, but we know that stretching them works. Do you care about the other parts of the bottling process?
