i know it is not a combination.
but on theory basis, it should be more than 4.8.
HKJC is giving a comparatively lower odds in this pool
I've amended the case study in order to give you a more clearer picture on why the odds is lower.
¥b³õ ©M $100 @ 2.05 + ¥þ³õ ©M $100 @ 3.3
Result
¥b³õ ©M + ¥þ³õ ©M => $535 [Odds: 535/200 = 2.675 < 4.8]
¥b³õ ¥D/«È + ¥þ³õ ©M => $330 [Odds: 330/200 = 1.650 < 4.8]
¥b³õ ©M + ¥þ³õ ¥D/«È => $205 [Odds: 205/200 = 1.025 < 4.8]
¥b³õ ¥D/«È + ¥þ³õ ¥D/«È => $0 [Total loss]
¥b¥þ³õ ©M-©M $100 @ 4.8
Result
¥b³õ ©M + ¥þ³õ ©M => $480 [Odds: 4.8]
¥b³õ ¥D/«È + ¥þ³õ ©M => $0 [Total Loss]
¥b³õ ©M + ¥þ³õ ¥D/«È => $0 [Total Loss]
¥b³õ ¥D/«È + ¥þ³õ ¥D/«È => $0 [Total loss]
For "¥b³õ ©M $100 @ 2.05 + ¥þ³õ ©M $100 @ 3.30", there are two more chances that you may not total loss and get back the money you bet on. Ofcoz' the winning odds for these 3 possibilities should be lower than "¥b¥þ³õ ©M-©M". Otherwise, the odds may become unreasonable.
