Risk

The notion of risk, I should point out, is inseparable from the ideas of probability and uncertainty. A person can't be said to be running a risk where an outcome is 100% certain. There is an old joke that makes this point rather neatly. A man jumps from the top of a hundred-storey skyscraper. As he passes each floor, on his way down, he says 'so far so good'... He acts as though he's making a risk calculation, but the outcome is in fact determined. (Giddens, 1999)
