The answer depends on whether the card(s) are drawn at random, whether it is a standard deck (or a pinochle deck), how many cards are drawn, if more than one then whether they are replaced before the next one is drawn. If 40 cards are drawn, without replacement, from a standard deck of cards, the probability of a card below 5 is 1: that is, a certainty. For a single random draw from a standard deck, the probability is 3/13 (Aces high) or 4/13 (Aces low).

If the pick is completely random, the deck is a standard deck and there are no jokers or any other cards other than the standard 52, the probability is 1/4
