📋 Steps

Understand decimal odds: a $10 bet at 2.50 returns $25 ($15 profit)

Convert fractional odds: 3/2 equals 2.50 decimal — profit equals stake times the fraction

Read American odds: +150 wins $150 on a $100 bet, -200 requires $200 to win $100

Turn odds into implied probability: 1 ÷ decimal odds = expected chance (2.50 → 40%)

Compare implied probability with your own estimate — higher estimate means the bet has value
