A dice has its faces named by alphabets H, I, J, X, Y and Z. Two positions of the same dice are given below. Which face is opposite to face Y?

To find the face opposite to Y, let's analyze the common face in both positions of the dice:
* The letter X is common to both positions.

From the properties of a standard/logical dice, any faces that are adjacent to a particular face cannot be opposite to it.

* In Position 1, the faces adjacent to X are H and Z.
* In Position 2, the faces adjacent to X are J and I.

Combining these observations, the faces adjacent to X are: H, Z, J, and I.
The only remaining face on the dice is Y.

Since Y cannot be adjacent to X, it must be located directly opposite to it. Therefore, the face opposite to face Y is X.
