Question 200287
P(King or Black) = P(King) + P(black)


P(King or Black) = (number of kings)/(total cards) + (number of black cards)/(total cards)



P(King or Black) = 4/52 + 26/52



Note: there are 4 kings (one of each suit) and 26 black cards (13 spades and 13 clubs). Also, there are a total of 52 cards in a deck.



P(King or Black) = (4+26)/52



P(King or Black) = 30/52



P(King or Black) = 15/26



So the probability is 15/26 which in decimal form is 0.5769 (which is 57.69%)
