Sorry for the lame title, couldn't thinnk of a better one xD
Anyways, can anyone please tell me how to solve this problem:
At a basketball tournament involving 8 teams, each team played 4 games with each of the other teams. How many games were played at this tournament?
The mark scheme says: since each team 4 games with other teams, 8*4= 32 games are played by each team. each game involved two teams, hence 32*(8/2)=128 games were played.
hmmm, so, if each team plays 4 games with each other team, but not itself (which is rediculous) , shouldn't it be 4*7=28 games each team, also, why do we divide the number of teams by two? I know it says there is two teams each match, but what effect why do we divide it by two?
Please help me, I am just confused, I just need a good explanation to remove this confusion.....
Thanks in advance
