6. Consider again the game in exercise 5 where player 1 moves first. But now suppose that, whatever 1 chooses, the probability that player 2 will correctly observe 1's action is 0.9, and there is probability 0.1 that player 2 will mistakenly observe the other action (which 1 did not choose). The payoffs depend on the players' actual choices according to the previous table (so, for example, if 1 chose T but 2 mistakenly observed B and chose R then 2's payoff would be 1). (a) Show the extensive-form game that describes this situation. (b) Show the normal representation in strategic form for the extensive-form game in part (a)
