Homework Help: Math

Posted by Emily on Thursday, September 13, 2007 at 10:59am.

Okay .. did you see my last answer? I think it is 5

But now I have another one and I think I know the answer but there is a trick question at the end. Maybe you can tell me if it is a trick or if it something I am missing.

A golf classic starts with 64 golfers. The golfers form pairs and each pair plays a match. The losers drop out and the winners of each pair then form new pairs and play again. Thenk those winners form pairs and play. this continues until there is one winner.
a) In how many matches must the winner play (and my answer is 5)

b)(the trick question)
How many matches are played by all the golfers to determine the winner?
Well it seems too easy to be real .. cuz I think it would be just one match since it says ALL golfers and after one match, half of them have to stop playing because they lost.
Am I right?
Thanks again.
