Guess the Toss

$A$ and $B$ are in a team called $AB$, playing against $C$. If team $AB$ wins it gets Rs $3$ (paid by $C$), nothing otherwise.
Game is: $A$ and $B$ may agree on a strategy beforehand, and are then placed in $2$ separate rooms far away with no way to communicate. $A$ will toss a fair coin and $B$ will also toss a fair coin; $A$ will have to guess the outcome of $B$'s toss and $B$ will guess $A$'s. If both guesses are right, team $AB$ wins Rs $3$, nothing otherwise. Should they play the game, if it costs them Rs $1$ paid to $C$ at the start?
