3. Analysis of the Arbitrage Opportunity
Positive Net Profit in All Outcomes
- Regardless of the game's result, there is a net profit of approximately $22, representing a return of over 2% on the total stake.
- This occurs because the winnings from the successful bet exceed the losses from the other, due to the specific odds and stake distribution.
Breakdown of Odds and Probabilities
- Bet 1 Odds (+120):
- Implied Probability = 100 / (Odds + 100) = 100 / (120 + 100) ≈ 45.45%
- Bet 2 Odds (-110):
- Implied Probability = (|Odds|) / (|Odds| + 100) = 110 / (110 + 100) ≈ 52.38%
- Total Implied Probability: 45.45% + 52.38% ≈ 97.83%
*Note: A total implied probability less than 100% suggests a theoretical arbitrage opportunity in sports betting.*
