1) LSU favored by 12.5 over Florida means that Vegas thinks there is about an 84% chance LSU wins.
2) Tennessee favored by 15 over Mizzou means that Vegas thinks there is about an 88% chance Tennessee wins.
3) Tennessee will presumably be favored similarly over Vanderbilt since Mizzou just beat them. So if we assume a 15 point spread, that is the same 88% chance.
.84 x .88 x .88 = 65.04%
