The cardinality of a set is defined as the number of distinct elements in that set.
In the set \( A = \{1, 3, 3, 4, 6, 7, 8\} \), the distinct elements are \( 1, 3, 4, 6, 7, 8 \). Therefore, the set can be simplified to:
\[ A = \{1, 3, 4, 6, 7, 8\} \]
This set contains 6 distinct elements.
Thus, the statement "Cardinality of set A = 7" is **False**.
