So there are 4 suits...each has 13 cards in it....13 * 4 = 52

We want...either a black card....or a face card.....we know the face cards are jacks...queens...kings

so there are 4 suits...and 3 face cards in each suit so 4 * 3 = 12 face cards...

we also want a black card if not a face card....there are *not counting face cards now* 

52 - 12 = 40 cards that are not face cards....there are only 2 suits that are red and 2 that are black...so we have

40 / 2 = 20 possible black cards...

so altogether

we have

20 black cards
and 12 face cards

20 + 12 = 32

this is out of ALL cards so

3252


simplify this down to get...???
