1) number of cards that aren't : number of cards that are 3 we have 48 cards that arent 3 and 4 cards that are. that means that odds are: 12:1 of not drawing 3
2) fallow same logic. its just opposite. 1:12
3) same logic. but there are only 2 black 7 cards which means that odds are: 50:2 or 25:1
Ok the answer of 6 are 12, 18, 24, 30, 36, 42, and 48. The multiples of 9 are 18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,162,171,180,189,198,. Hope it helps!
