The ratio of the expected player loss to the total amount bet. This is a good measure of comparing the value of one bet against another. For games in which there is no raising the element of risk will be the same as the house edge. However for games in which the player may increase his bet the element of risk will be lower. For example in Caribbean Stud Poker the house edge is 5.22%. However the average amount bet per hand is 2.0445 times the initial bet, so the element of risk would be 0.0522/2.0445 = 2.55%.
