Two players A and B play a match. Which consists of a series of games (independent). Whoever first wins two games not necessarily consecutive, wins the match. The probability of A's winning, drawing, losing a game against B are (1)/(2), (1)/(3), (1)/(6) respectively. It is known that A won the match at the end of 11^(th) game, the probability that B wins only one game is (A) (3)/(11) (B) (8)/(11) (C) (9)/(11) (D) (10)/(11)
