You are dealt one card from a​ 52-card deck. Find the probability that you are dealt a king or a black card.

There are 26 black cards  + 2 additional   red kings   for a total of  28 cards  out of 52 which will meet your criteria

 

28/52 = 7/13

So a 52 card deck, and we want to find the probability of being dealt a king or a black card.

 

Well, there are 4 kings, hearts, clubs, diamonds, and spades (not in order).

 

And there are 26 black cards INCLUDING 2 kings.

 

So it's 26 black cards (including king) + 2 red kings = 28.

 

So 28/52 OR 7/13 which is the same as EP! laugh
