A standard deck of cards has 52 cards, with 13 cards in each of the four suits: spades, hearts, diamonds, and clubs. The probability of drawing a spade is 13/52, and the probability of drawing a heart is also 13/52. Since these two events do not overlap (a card cannot be both a spade and a heart), you can add these probabilities together to find the probability of drawing either a spade or a heart: (13/52) + (13/52) = 26/52 = 1/2 = 0.50.
