"Alternatives" imply the addition principle "Sequence of steps" implies the multiplication principle STEP 1 : select a denomination (not Aces, so 12 to choose from) ...C(12,1) STEP 2 : select 3 (out of 4 cards of that denomination) ...C(4,3) STEP 3 : select 2 different denominations from the remaining 11 ... C(11,2) STEP 4 : select 1 card of the 1st denomination chosen in (3) ...C(4,1) STEP 5 : select 1 card of the 2nd denomination chosen in (3)...C(4,1) TOTAL: (multiplication principle) = C(12,1)C(4,3)C(11,2)C(4,1)C(4,1)
