There are 52 cards in a deck of cards.
In a standard deck of playing cards, there are 52 cards in total. If we consider only the cards that are larger than 9, we are looking at the 10, Jack, Queen, King, and Ace of each suit. This gives us 5 cards per suit, totaling 20 cards larger than 9 in the entire deck.
There is only one 9 of diamonds in a standard deck of 52 playing cards. Each rank and suit combination appears only once in the deck. Therefore, you'll find just one 9 of diamonds alongside the other cards.

There are four 5 and four 9 cards. Thus 8 out of 52 cards are 5 or 9.
In a standard deck of cards, there are 52 cards. The square numbers among these are 1 (Ace), 4 (4), 9 (9), 16 (King of Hearts, as there are no 16s in a standard deck), and 25, but only up to 10 can be represented, making 1, 4, and 9 the only square numbers. Therefore, there are three square numbers in a standard deck of cards: 1, 4, and 9.
The probability of drawing 3 cards, all with the value of 9, from a standard 52 card deck, is ~0.018%.
