There are \(17\) teams. It requires \(2\) teams for game, so there will be \(\binom{17}{2} = 136\) games in total.

Can u tell me how to do graph
ganeshie8
  • ganeshie8
Call the teams with numbers and put them in a circle so that the graph looks neat |dw:1438552119794:dw|
ganeshie8
  • ganeshie8
Btw, those numbers are vertices and they represent the 17 teams.

team \(\color{blue}{1}\) plays one game with each of the 16 other teams, yes ?
anonymous
  • anonymous
cool,
ganeshie8
  • ganeshie8
so draw an edge between team \(\color{blue}{1}\) and each of the other 16 teams : |dw:1438552375693:dw|
ganeshie8
  • ganeshie8
each edge represents a "game" between the vertices it connects
ganeshie8
  • ganeshie8
Notice that in team \(\color{blue}{1}\) has played with 16 other teams, so there are 16 edges
anonymous
  • anonymous
thanks a lot, :)
ganeshie8
  • ganeshie8
thats not the complete graph, next you pretend that team 1 is not there, and draw edges from team 2 to remaining 15 other teams
anonymous
  • anonymous
yes i got it now
ganeshie8
  • ganeshie8
|dw:1438552756905:dw|
ganeshie8
  • ganeshie8
Notice that \[16+15+14+\cdots +3+2+1 = 136\]
