Reasonable parlay odds

All 2 legs must win. At 3.60× combined odds the parlay has just a 27.8% implied chance of paying out.

Leg 1 · 2.00×2.000

Leg 2 · 1.80×3.600

Each leg's odds multiply together — all legs must win for the parlay to pay. More legs mean a bigger payout but a lower chance of winning.
