3. Consider the same game as in question 2 above, but suppose T is not known. Instead, we know that the game continues with probability & and ends with probability 1 - S after each round with each player getting zero if the game ends (or, if you prefer, d is the discount factor. (a) (15%) Is it possible to play (B, b) in each period if S = 0.8? (b) (10%) What if S = 0.2
