To get a number point 1 is impossible for any of the team to reach at the end of the described tournament.
As given in the question,
Total number of footballs teams = 3
Each team plays once with other team
Let three teams are Team1, Team2, and Team3
Team1 plays with Team2 and Team3
Team2 will play with Team3
Winning points = 3
Losing team points = 0
Withdraw teams points = 1
To reach in finals suppose Team1 plays with Team2 and Team3 and win
Points of team1 = 3 + 3
= 6points
As team plays once with other team , Team1 is out of the game.
Team2 and Team3 play with each other
To reach at the end of the tournament one team has to win let it be Team2
Points of Team2 = 3
Points of Team3 = 0
No withdraw game is possible to reach into finale.
Therefore, point 1 is impossible for any team to reach at the end of the tournament.
