Let's go through each question using the information in the image.

### Solution:

1. **Total Cards**: A standard deck has 52 cards.

#### (a) What is the probability that the card drawn is a heart?

- There are 13 hearts in the deck (one for each rank: Ace, 2, 3, ..., King).
- Probability \( P(\text{Heart}) = \frac{\text{Number of Hearts}}{\text{Total Cards}} = \frac{13}{52} = \frac{1}{4} \).

**Answer for (a):** \(\frac{1}{4}\).

#### (b) What is the probability that the card drawn is a four?

- There are 4 fours in the deck (one in each suit: Hearts, Diamonds, Spades, Clubs).
- Probability \( P(\text{Four}) = \frac{\text{Number of Fours}}{\text{Total Cards}} = \frac{4}{52} = \frac{1}{13} \).

**Answer for (b):** \(\frac{1}{13}\).

#### (c) What is the probability that the card drawn is a heart and a four?

- There is only one card that is both a heart and a four (the Four of Hearts).
- Probability \( P(\text{Heart and Four}) = \frac{\text{Number of Fours of Hearts}}{\text{Total Cards}} = \frac{1}{52} \).

**Answer for (c):** \(\frac{1}{52}\).

### Tip:

In probability, if you want to find the probability of drawing either of two types of cards, you can add their individual probabilities only if there’s no overlap between the two categories.

Suppose one card is drawn at random from a standard deck. What is the probability that the card drawn is a heart? What is the probability that the card drawn is a four? What is the probability that the card drawn is a heart and a four?

Explore the probabilities of drawing a heart, a four, and a heart that is also a four from a standard deck of 52 cards. This problem covers basic probability concepts suitable for students in Grades 5-7.
