An ordinary deck of cards contains 52 cards divided into four suits. The red suits are diamonds (◆) and hearts (♥), and the black suits are clubs (♣) and spades (♠). Each suit contains 13 cards of the following denominations: 2, 3, 4, 5, 6, 7, 8, 9, 10, J (jack), Q (queen), K (king), and A (ace). The cards J, Q, and K are called face cards.
Imagine choosing a card at random from a thoroughly mixed deck. Consider the event that the denomination of the chosen card is at most 4 (counting aces as 14).
What is the probability of this event?
