    A p=12/13, q=7/11 Correct Answer Incorrect Answer
    B p=1/13, q=5/11 Correct Answer Incorrect Answer
    C p=10/11, q=5/7 Correct Answer Incorrect Answer
    D More information needed Correct Answer Incorrect Answer
    E Doesn’t exist Correct Answer Incorrect Answer

    Solution

    Payoff of pred when Playing active is 2p+9(1-p); When playing passive is 3p-(1-p). Payoffs should be equal since the pred should be indifferent. Hence solving for p we get p=10/11. Solving in a similar way we get q=5/7. Mixed strategy Nash equilibrium is p=10/11; q=5/7.
