Question 873384: There are 52 cards in the standard deck of cards.
26 of them are red: 13 Hearts ©, 13 Diamonds ¨.
26 cards are black: 13 Clubs ♣, 13 Spades ª.
Each of these four groups have King card.
So, there are four Kings in the deck of cards: 2 red and 2 black.
Find the probability that randomly taken card will be King or red.
Use formula: P(A or B) = P(A) + P(B) - P(A and B).
Simplify the final fraction.
