From the given scenarios, the positions of winning of each team is; Team C came first, Team A came second and Team B came third
<h3>How to find probability of winning?</h3>
From the question, we can derive the following;
Marks gained by team A = 3 × 20 = 60 marks
Marks deducted = 2 × 10 = 20 marks
Hence;
Total marks for Team A = 60 - 20 = 40 marks
Marks gained by team B = 2 × 20 = 40 marks
Marks deducted = 2 × 10 = 20 marks
Hence, total marks of team B = 40 - 20 = 20 marks
Marks gained by team C = 3 × 20 = 60 marks
Marks deducted = 1 × 10 = 10 marks
Hence, total marks of team C = 60 - 10 = 50 marks
Thus, we can conclude that;
Team C came first, Team A came second and Team B came third
