23. Assume that Bob and Carol view the cake as in Exercise 22, but assume also that each knows how the other values the cake, and that neither is spiteful. Suppose they are to divide the cake using the rules, but not necessarily the strategies, of divide-and-choose. Is Bob better off being the divider or the chooser?
23.
Bob should be the divider. That way, he can get 12 units of value instead of 9 units of value.
