**Question:**
What is the Cartesian product of A, B, and C, where:
- \( A = \{1, 2\} \),
- \( B = \{x, y\} \),
- \( C = \{0, 2\} \)?

The Cartesian product \( A \times B \times C \) includes all possible ordered triples formed by selecting one element from \( A \), one from \( B \), and one from \( C \).

Let's solve this step by step:

### Solution:
Given:
- \( A = \{1, 2\} \),
- \( B = \{x, y\} \),
- \( C = \{0, 2\} \),

The Cartesian product \( A \times B \times C \) is the set of all ordered triples \((a, b, c)\) such that \( a \in A \), \( b \in B \), and \( c \in C \).

We can now compute all combinations:

- From \( A = \{1, 2\} \),
- From \( B = \{x, y\} \),
- From \( C = \{0, 2\} \),

The possible triples are:

1. \( (1, x, 0) \),
2. \( (1, x, 2) \),
3. \( (1, y, 0) \),
4. \( (1, y, 2) \),
5. \( (2, x, 0) \),
6. \( (2, x, 2) \),
7. \( (2, y, 0) \),
8. \( (2, y, 2) \).

Thus, the Cartesian product is:
\[
A \times B \times C = \{(1, x, 0), (1, x, 2), (1, y, 0), (1, y, 2), (2, x, 0), (2, x, 2), (2, y, 0), (2, y, 2)\}
\]

### Tip:
The size of the Cartesian product of sets \( A \), \( B \), and \( C \) is the product of their cardinalities. For instance, if \( |A| = 2 \), \( |B| = 2 \), and \( |C| = 2 \), then \( |A \times B \times C| = 2 \times 2 \times 2 = 8 \).
