The following are examples of identical teams A---W---A (Adult vs. Adult) C-T---W---C-T A-T-C-C---W---C-C-T-A a. Describe three distinct ways to arrange the teams so that you get a tie even though the teams have different numbers of players. These are non-identical, balanced teams. (To show distinct arrangements, don't simply switch players on each side. For example, A-C---W---T and T---W---A-C are not distinct. (Nor do they produce a tie.)
