There is a better way to phrase this question. It's a well known test of statistics students' idiocy, apparently. Read it recently on this blog, I think:

Something like: how much cash would make you accept a 1/20000 chance of immediate death?
My correct answer ('my answer' because we have to be intolerably conceited in this forum, I understand) is "the smallest amount of cash that means something to me... about 60 quid, which I can buy sex with."
Apparently many students would decline any amount of cash!
