Assuming face cards are not counted as denominations...
then the even # cards are 2,4,6,8,10, with four of each denomination
4/52 * 20/51 = 1/13 * 20/51 = 20/663 which is just over 3%
Assuming face cards ARE counted as denominations, then queen and high ACE are added
to this list...
4/52 * 28/51 = 1/13* 28/51 = 28/663 , which is just over 4.22%
