I'm trying to figure the fair odds for winner of more oscars Avatar vs Hurt Locker. Pinny has Avatar to win over 4.5 oscars at +103 and under at -120. They also have Hurt Locker to win over 3.5 oscars at -228 and under at +191. Can I use this info to create a fair line for most oscars won between the two? How do I go about this and what math functions should I be looking at?
