Since half the deck is red, the probability of getting a red card = 1/2 

There are 4 faces cards of each suit (4 Jacks, 4 Queens, 4 Kings), so the probability of picking one of those is  = (4+4+4)/52 = 12/52 

So, the probability of getting a red card OR face card means you must use the "addition" rule, so add the 2 probabilities: 

1/2 + 12/52 = 13/26 + 6/26 = 19/26
