The payoff matrix for a two$-$player normal form game is given below.

$\backslash$table$[[,$A$],[$B$,$C$],[$M$,12],[45,63],[$N$,22],[51,24],[$O$,42],[15,73],[,],[,]]$

Denote the probability of playing $"$ M $"$ for Player $1$ as p and the probability of playing $"$ B $"$ for Player $2$ as q$.$ At which value of q will Player $1$ be willing to mix between M and N $?$

Write your answer as a decimal number with $2$ decimal places $($e$.$g$.0\mathrm{.}05)$
