can you explain your approach please?
Let A has to win the game and also assume that till the last game the winner is not decided.
Then MAXIMUM number of games to be played = 7
The winners of the games in the order is: ABABABA
7th game is deciding the winner. (7 possibilities here
So any other possibility will decide the winner in less than 7 games.
Hence 7 games are to be played at max to decide "A" as the winner.
Similarly if the order is altered (BABABAB)
B will be winner in the 7th game.( 7 possibilities here
So TOTAL 14 NUMBER OF POSSIBILITIES TO SELECT THE WINNER.
