यदि (n\(A\cup B\cup C\)=95), ठीक एक में (46), ठीक दो में (33) हैं, तो (n\(A\cap B\cap C\)) कितना है?

If (n\(A\cup B\cup C\)=95), exactly one has (46), and exactly two has (33), what is (n\(A\cap B\cap C\))?

Explanation opens after your attempt
Correct Answer

A. (16)

Step 1

Concept

Union equals exactly one plus exactly two plus all three, so all three is (95-46-33=16). These region categories are disjoint.

Step 2

Why this answer is correct

The correct answer is A. (16). Union equals exactly one plus exactly two plus all three, so all three is (95-46-33=16). These region categories are disjoint.

Step 3

Exam Tip

संघ (=) ठीक एक (+) ठीक दो (+) तीनों, इसलिए तीनों (95-46-33=16)। क्षेत्र श्रेणियां अलग-अलग होती हैं।
