Probably a silly question.
But when a team +0.50 I know that means that you have the win and draw in your favour.
If you back a team that is -0.50 then they have to win.
But why is there different odds for -0.25 and +0.25 and -0.75 and +0.75 etc?
If a team wins by one goal then aren't all the outcomes the same?
