यदि (n(A)=8), (n(B)=6) और (n\(A\cup B\)=10) हैं, तो (n\(A\cap B\)) क्या है?

If (n(A)=8), (n(B)=6), and (n\(A\cup B\)=10), what is (n\(A\cap B\))?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

(n\(A\cap B\)=n(A)+n(B)-n\(A\cup B\)). Hence (8+6-10=4).

Step 2

Why this answer is correct

The correct answer is A. (4). (n\(A\cap B\)=n(A)+n(B)-n\(A\cup B\)). Hence (8+6-10=4).

Step 3

Exam Tip

(n\(A\cap B\)=n(A)+n(B)-n\(A\cup B\)) होता है। अतः (8+6-10=4) है।
