यदि (n(U)=150), (n(A)=91), (n(B)=86) है, तो (n\(A\cup B\)) का न्यूनतम संभव मान कितना है?

If (n(U)=150), (n(A)=91), (n(B)=86), then what is the minimum possible value of (n\(A\cup B\))?

Explanation opens after your attempt
Correct Answer

A. (91)

Step 1

Concept

The minimum union can be as small as the larger set, which is (91). This is possible when \(B\subseteq A\).

Step 2

Why this answer is correct

The correct answer is A. (91). The minimum union can be as small as the larger set, which is (91). This is possible when \(B\subseteq A\).

Step 3

Exam Tip

संघ का न्यूनतम मान बड़े समुच्चय जितना हो सकता है, यानी (91)। ऐसा तब संभव है जब \(B\subseteq A\) हो।
