 (Why “expected” utility? If you faced the same decision problem over and over again, and each time you chose option \(A\), in the long run you could expect your average utility to be approximately \(EU(A)\).) The same idea extends to cases with more than two ways things could turn out simply by adding columns to the table and multiplying/summing all the way across. When there are more than two possible actions, we just add more rows and do the same.
