Question

Sixty-four players signed up for a tennis tournament. A player is eliminated upon losing a match. How many matches must be scheduled to determine the tournament champion?

Answer 1

so it needs to be:
64/2=32
32/2=16
16/2=8
8/2=4
4/2=2
2/2=1

So there need to be 7 rounds.

Hope this helps :)
