This is exactly my reaction too: when faced with any situation where another agent might influence outcomes, people naturally think more in terms of game theory and minimaxing than probabilities. (Of course, here minimaxing is applied to probabilistic gambles, but the volunteer presumes the “30 red balls” rule to be less subject to manipulation than the balance of green vs. blue.)
