Question

If Set A has the unique elements {2, 3, 5}, which of the following correctly represents its cardinality?

Options

• A = 3

• n(A) = 10

• n(A) = 3

• n(3) = A

Answer 1

n(A) = 3

Explanation:

The set contains exactly three distinct items (2, 3, and 5). Therefore, the notation for its count is n(A) = 3.
