and

These behavior strategies indicate that Mark will choose randomly among his three actions, each with the same probability, and Ben will randomly choose No or Hi with equal probabilities at the information set Ben1 but will be twice as likely to choose Hi over No at the information set Ben2. The probabilities for behavior strategies are displayed below the edges in Figure 6.20. If the players choose the strategy profile s,
