Football teams `T_1 and T_2` have to play two games against each other. It is assumed that the outcomes of the two games are independent. The probabilities of `T_1` winning, drawing and losing a game against `T_2` are `(1)/(2),(1)/(6) and (1)/(3)` respectively. Each team gets 3 points for a win. 1 point for a draw and 0 point for a loss in a game. Let `X and Y` denote the total points scored by teams `T_1 and T_2` respectively. after two games. `P(X=Y)` is
A. `(11)/(36)`
B. `(1)/(3)`
C. `(13)/(36)`
D. `(1)/(2)`
