Verified step by step guidance1
Identify the total number of cards in a standard deck, which is 52.
Determine the number of face cards in the deck. Face cards include Jacks, Queens, and Kings. Since there are 4 suits and each suit has 3 face cards, calculate the total face cards as \(4 \times 3\).
Calculate the number of cards that are NOT face cards by subtracting the number of face cards from the total number of cards: \(52 - (4 \times 3)\).
Express the probability of drawing a non-face card as the ratio of non-face cards to the total number of cards: \(\frac{\text{number of non-face cards}}{52}\).
Simplify the fraction if possible to get the final probability in simplest form.
