Who is favored to win? According to Bookmaker 2, Nacional is the favorite with odds of 2.35. This implies a 43% chance of winning (possible). A £10 bet would return £23.50 if they win (£13.50 profit).
What about Tondela? The odds of 3.20 suggest a 31% chance of winning (unlikely). However, if you bet £10 and they win, you'd get £32.00 back (£22.00 profit) — higher risk, higher reward.
How likely is a draw? Draw odds of 3.10 imply a 32% probability. A £10 bet on a draw would return £31.00 if correct (£21.00 profit).
How to read odds: Lower odds = more likely to happen (but smaller payout). Higher odds = less likely (but bigger payout if correct). Multiply your stake by the odds to calculate your total return.
