Answer:
1. Please find it attached.
If both of them don't get lawyers they will each make half of the $5 million being $2.5 million a piece.
If one side hires a lawyer and the other doesn't, the side with the lawyer will win 0.9 of $5 million which is $4,500,000. However they would have paid the lawyer $200,000 so that payout drops to $4,500,000. The other would make 0.1 which is $500,000.
If they both get a lawyer they will each get half which is $2,500,000 but they would both have paid their lawyers $200,000 a piece so the net payout would be $2,300,000.
2. The Nash Equilibrium is the alternative that it would not serve either party to deviate from as it serves them both well. The Nash Equilibriums would be If both don't get a lawyer or if both get a lawyer.
3. Yes they would because without lawyers they would make more money as they would not have to pay the $200,000 in fees.
