Asuming that all the teams have the same skill levels the game will mostly be chance. The chance of winning will be 1/12 because they are 1 out of 12 teams.
Let the three consecutive integers be x , x+1 ,x+2 Given, sum of three consecutive integers = -126 x +x+1+ x+2 = -126 3x +3 = -126 3x = -126 -3 3x = -129 x = -129/3 x = - 43 x +1 = -42 x +2 = -41
