Answer:
1/13
Explanation:
Since there are 4 suits (Clubs, Spades, Diamonds, Hearts) in total, with 2 of them being black and 2 being white, that means that each subset has 26 cards. Of these, 2 of them are either kings or jacks, depending on which subset you look at. There are 2 black kings and 2 red jacks in a regular deck of cards. The probability starts as 4/52, which is simplified to 2/26 and is finalized as 1/13. Convert to a percentage if necessary.
