I'd take the 5000$ (which is sure) because of mathematics: 50% chance to have 8000 means you'll get 8000 or nothing, so the average is (8000+0)/2 = 4000 which of course is less than 5000! If I correctly understood the 2nd question, I'd explain it like this: if you're greedy you want more and more, so you don't mind to take some risk in order to get it; you're adventurous, then, and try to win those 8000$. While if you're conservative you're very careful and usually avoid takeing risks, so you're satisfacted with what you have, contented. PS: I just love your young Amélie Poulain's picture!

Without effort of mine own, i will take the chance of $8000. Indeed, greed or adventurous or conservative or contentment is about the heart's desire. Only yourself or GOD knows your heart. Something we human can even cheat (or convince) ourselves. For example, you can say my decision is greed, but my heart convince me that I am adventurous... I might be lying to myself, only GOD knows...

maybe i think most of the people will choose the 5000 dollars ,choose what we can do things better than what we just expect things, so i prefer chose the 100% chance ,maybe this is a perfect choose! :)

I'd definetly take the $5000. I'm not that lucky :P It would have to be something like 100% $5000 vs 50% $30,000 before I'd really be tempted. There is just so much I could do with $5000, there would be no sense in risking it.
