XA + XB = 1 XA + XB 1 XA + XB 1 XA + XB = 2 (b) At least one of the decisions A and B should be chosen; and both can be chosen together. (c) At least one of the decisions A and B should be chosen; and both should not be chosen together. (d) Each of the decisions A and B can be chosen individually; and both should not be chosen together. (e) B can be chosen when A is chosen; but A should be chosen when B is chosen.
