His example was kind of confusing, since you'd want the money, but not to get shot. So it's kind of reversed.
So take his example, but imagine it's a bad outcome. Perhaps you have to pay the amount of money under the cup. The majority (98 red cups) have more overall money penalties, but spread out among more cups. A tiny minority (2 green cups) have less overall penalties, but it's a lot more concentrated. Assuming you averaged everything out, picking a green minority cup you'd have to pay $50, picking a red majority cup you'd have to pay $2...despite the red majority having twice as much penalties overall.
