Probability worksheet with card-related questions for calculating chances from a 52-card deck.

Let’s solve each probability question step by step.

We’re working with a standard deck of 52 playing cards.
That means:
- There are 4 suits: hearts, diamonds, clubs, spades.
- Each suit has 13 cards: Ace through 10, Jack, Queen, King.
- So total = 4 × 13 = 52 cards.

Probability is calculated as:

> Probability = (Number of favorable outcomes) ÷ (Total number of possible outcomes)

In this case, total outcomes = 52 (since we’re picking one card from the whole deck).

1. a Jack

There are 4 Jacks in a deck (one per suit).
So probability = 4/52 → simplify by dividing numerator and denominator by 4 → 1/13

---

2. a club

There are 13 clubs (all cards in the club suit).
Probability = 13/52 → simplify → 1/4

---

3. a King

Same as Jack — 4 Kings in the deck.
Probability = 4/52 → 1/13

---

4. Queen

Again, 4 Queens.
Probability = 4/52 → 1/13

---

5. Not a picture card

Picture cards = Jack, Queen, King → 3 per suit × 4 suits = 12 picture cards.

So NOT picture cards = 52 - 12 = 40 cards.

Probability = 40/52 → simplify by dividing by 4 → 10/13

6. A king or queen

Kings = 4, Queens = 4 → total = 8 cards.

Probability = 8/52 → simplify by dividing by 4 → 2/13

---

7. Seven of spade

Only ONE seven of spades in the deck.

Probability = 1/52 → already simplified → 1/52

---

8. An ace

4 Aces in the deck.

Probability = 4/52 → 1/13

---

9. Diamond ace

This means the Ace of Diamonds — only 1 such card.

Probability = 1/52 → 1/52

---

10. King of clubs

Only one King of Clubs.

Probability = 1/52 → 1/52

1. 1/13

3. 1/13
4. 1/13
5. 10/13
6. 2/13
7. 1/52
8. 1/13
9. 1/52
