Let a card be drawn at random from an ordinary deck of 52 playing cards. Then the sample space S is the set of m = 52 different cards, and it is reasonable to assume that each of these cards has the same probability of selection, 1/52. Accordingly, if A is the set of outcomes that are kings, then P(A) = 4/52 = 1/13 because there are h = 4 kings in the deck. That is, 1/13 is the probability of drawing a card that is a king, provided that each of the 52 cards has the same probability of being drawn.
