Step 1: Understanding the Concept:
This is a standard dice problem. By comparing different positions where certain faces are common, we can determine adjacent and opposite faces.
Step 2: Detailed Explanation:
1. Look at position 1 and position 4. Both have faces '3' and '2' in common.
2. Rule of Dice: If two faces are common in two different positions of the same dice, then the third remaining faces are opposite to each other.
3. In position 1, the faces are 3, 2, and 4.
4. In position 4, the faces are 3, 2, and 1.
5. Since 3 and 2 are common to both, the remaining faces 4 and 1 must be opposite to each other.
Step 3: Final Answer:
The number on the face opposite to 4 is 1.
