I don't think this is particularly difficult, unless I've misread the problem. we want the probability of drawing a card and having it be something other than a heart or king. 4 kings total, 13 hearts total, but that double counts the king of hearts. so we have 13+4-1=16 "bad" cards. there are 52 total. so, probability of not getting them is (52-16)/52.
