Question
Let A = {HT}, B = {1, 2, 3, 4, 5, 6}, and C = {red}. Find the number indicated.
n(A ✕ C ✕ C)
 
**Educational Content: Understanding Cartesian Products**

Given sets:
- \( A = \{ H, T \} \)
- \( B = \{ 1, 2, 3, 4, 5, 6 \} \)
- \( C = \{ \text{red} \} \)

**Objective:** Find the number of elements in the Cartesian product \( A \times C \times C \).

**Explanation:**
- A Cartesian product of sets is an ordered pair of sets that provides all possible combinations of elements.
- \( A \times C \times C \) means we are creating ordered triples where the first element is from set \( A \), the second and third elements are from set \( C \).

**Steps:**
1. Since \( A \) has 2 elements, and \( C \) has 1 element, \( C \times C \) will have \( 1 \times 1 = 1 \) element.
2. Therefore, \( A \times C \times C \) = \( 2 \times 1 = 2 \) combinations.

**Conclusion:**
The number of elements in \( A \times C \times C \) is **2**.
