Who is favored to win? According to Bookmaker 2, Inter is the favorite with odds of 1.70. This implies a 59% chance of winning (more likely than not). A £10 bet would return £17.00 if they win (£7.00 profit).
What about Napoli? The odds of 5.25 suggest a 19% chance of winning (very unlikely). However, if you bet £10 and they win, you'd get £52.50 back (£42.50 profit) — higher risk, higher reward.
How likely is a draw? Draw odds of 3.50 imply a 29% probability. A £10 bet on a draw would return £35.00 if correct (£25.00 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.
