How is that decision eliminated? It is eliminated by choosing the values that maximize the utility. For example, if rentGame=T and outcome=Like, then buying the game results in a utility of 52.4 whereas not buying the game results in a utility of only 19.8. So we add a new decision function to our set of decision functions, specifying that when the parents have those assigned values, the decision is to buy the game. This is done for each combination of parent values.
