Pavlock VS Martinez
 

The fight tonight has a -155 pavlock +125 Martinez betting ods. What does this mean? That Pavlock is 3 times more likely to win? Also, a hypathetical situation if my friend wanted to bet me $10 that Martinez would win should I take the bet if Pavlik wins I get $10 and if he loses I give my friend $10 if Martinez wins? If the betting ods are -155 Pavlock and +125 Martinez would I give my friend $30. If we were useing las Vegas betting ods?
