Hanafuda is a japanese game that uses a deck of cards made up of 12 suits, with each suit having four cards. How many 7-card hands can be formed so that 3 are from one suit and 4 are from another?
-----------------
Pick a suit: 12 ways
Pick 3 from that suit: 4C3 = 4 ways
Pick a 2nd suit: 11 ways
Pick 4 from that suit: 4C4 = 1 way
----------------------------------------
Total # of hands: 12*4*11*1 = 528
