P%28K%29=4%2F52=1%2F13
P%28H%29=13%2F52=1%2F4
P%28R%29=26%2F52=1%2F2
You add all of the probabilities and then subtract to account for double counts.
Since all hearts are red, you subtract 1/4.
Since the king of hearts and the king of diamonds are both red, you subtract 2/52.
P%28K+or+H+or+R%29=4%2F52%2B13%2F52%2B26%2F52-13%2F52-2%2F52=28%2F52=7%2F13
