Imagine you have $10k to your name and flip a coin for $1k.
Your expected value in money terms is $9k * 0.5 + $11k * 0.5.
Your expected value in utility terms is: u($9k) * 0.5 + u($11k) * 0.5 where u is a function that tells you how much worth you get from money. See wikipedia link for some explanation (although I think the articles are over-complicated and don't convey the point in clear way):

The key point is that utility is concave (a coin flip for any amount has negative utility) which is obvious when you think about it (better to be a millionaire than flip a coin to be busted or have 2 million net worth) but maybe not something most people think when making everyday decisions.
