Answer

To solve the question, we need to analyze the number of children in the families and find out how many families have 2 children and how many families have the same number of children.

### Step-by-Step Solution:

1. **List the Data**: We have the following number of children in 12 families:
- 3, 1, 4, 1, 2, 2, 3, 1, 2, 2, 3, 3

2. **Count the Number of Families for Each Number of Children**:
- **1 child**: Count how many times '1' appears in the list.
- From the list: 1, 1, 1 → There are **3 families** with 1 child.
- **2 children**: Count how many times '2' appears in the list.
- From the list: 2, 2, 2, 2 → There are **4 families** with 2 children.
- **3 children**: Count how many times '3' appears in the list.
- From the list: 3, 3, 3, 3 → There are **4 families** with 3 children.
- **4 children**: Count how many times '4' appears in the list.
- From the list: 4 → There is **1 family** with 4 children.

3. **Summarize the Counts in a Table**:

| Number of Children | Number of Families |
|--------------------|--------------------|
| 1 | 3 |
| 2 | 4 |
| 3 | 4 |
| 4 | 1 |

4. **Compare the Counts**:
- We see that the number of families with 2 children is **4**.
- We also see that the number of families with 3 children is **4**.

5. **Conclusion**:
- The number of families with 2 children is equal to the number of families with **3 children**.

### Final Answer:
The number of families with 2 children is equal to the number of families with **3 children**.
