A team which gets a bye will not play in the first round. Bye is a privilege given to a team generally by drawing of lots, exempting it from playing a match in the first round.
Method of deciding Bye: We check whether teams participating is a power of two or not. Such as 2, 4, 8, 16, 32, 64, 128 etc. In case the team is not a power of two then Bye shall be given. e.g., if number of teams participating are 13. Next higher power of two is 16.
Number of Bye = 16 – 13 = 3 Bye
