It's a joke...Gambler's "Fallacy" and all. If you want to be purely empirical then everyone has pretty much 10% chance of being chosen. Everything else is just an assumption that the DM will prioritize mechanically diversity in favor of character diversity. But actually relying on statistics would be both way too much work and mostly fruitless since the decision is based largely on unquantifiables. Basically what I'm saying is: STRAP IN KIDDOS, MATH CAN'T SAVE YOU NOW. |
