Sevnety-eight players entered a single elimination tennis tournament.How many matches were played to determine the overall champ?

Question

please help me...and if u get the answer can you explain how you got it with a rule or a pattern

Answer 1

Usually in a single elimination, the number of players is a power of 2,
if not, there will have to be "byes".
e.g. the French Open has 128 starting competitors, or 2^7

You have 78 players, so the first round would have
39 matches with 39 remaining winners.

So there will have to be some rules stated for byes.

Answer 2

what ????this is so confusin
