I agree completely with a minor tweak: "Would you RISK $900 for a 90% chance to win $1000?" "Would you RISK $100 for a 10% chance to win $1000?"

It's all about managing the risk: generally speaking, I can afford to risk $100, but not $900. Furthermore, I've already spent/borrowed the second $1000 (We're TAKING my existing money, which I presumably have already planned on having). So the first is a windfall, but the second is a real need. So I WON'T risk a large amount of money for a windfall, but I WILL risk a small amount in order to meet a real need. I'd say that's 100% rational.
