Here is the payoff matrix for a two player normal form game

1,2 4,5 6,3 2,2 5,1 2,4 4,2 1,5 7,3 Denote the probability of playing I'M" for Player 1 as p and the probability of playing "B" for Player 2 as q. Given q 2 0. what is the highest value of q for which playing 0 maximises Player 1's utility (that is. playing 0 is at least the equal-best choice)? Write your answer as a decimal number with 2 decimal places (e.g. 0.05)
