Ok i need someone to help me figure this out since math isn't my strong point

I do weekly sports bets on football and thought of a perm idea

Now i want to pick 12 games and in each game there are 3 outcomes: win, lose and draw

Obviously you cannot select more than one outcome for each match per bet such as say Chelsea to win and Chelsea to draw in same bet

How many possible combinations are their with 12 teams (3 outcomes) without duplicating?
