किसी भी समुच्चय (A) के लिए (n\(A\cap A^c\)) कितना होता है?

For any set (A), what is (n\(A\cap A^c\))?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

\(A\cap A^c=\varnothing\), so it has no element. Hence its cardinality is (0).

Step 2

Why this answer is correct

The correct answer is A. (0). \(A\cap A^c=\varnothing\), so it has no element. Hence its cardinality is (0).

Step 3

Exam Tip

\(A\cap A^c=\varnothing\), इसलिए इसमें कोई तत्व नहीं होता। अतः इसकी संख्या (0) है।
