Don, Dale, and Cam buy a carton of neopolitan ice cream that is one-third chocolate, one-third vanilla, and one-third strawberry as shown below. They wish to fairly divide the ice cream using the lone chooser method. Don likes chocolate twice as much as vanilla or strawberry. Dale likes strawberry but no other flavor. Cam, the chooser, likes chocolate and vanilla twice as much as strawberry. In the first division, Don cuts the chocolate piece off and lets Dale choose his favorite piece.
