यदि (n(A)=102), (n(B)=95), (n\(A\cup B\)=143) और (n(U)=190) है, तो (n\(A^c\cap B^c\)) कितना होगा?

If (n(A)=102), (n(B)=95), (n\(A\cup B\)=143), and (n(U)=190), what is (n\(A^c\cap B^c\))?

Explanation opens after your attempt
Correct Answer

A. (47)

Step 1

Concept

(A^c\cap B^c=\(A\cup B\)^c), so (190-143=47). Use De Morgan's law to identify the outside region.

Step 2

Why this answer is correct

The correct answer is A. (47). (A^c\cap B^c=\(A\cup B\)^c), so (190-143=47). Use De Morgan's law to identify the outside region.

Step 3

Exam Tip

(A^c\cap B^c=\(A\cup B\)^c), इसलिए (190-143=47)। डी मॉर्गन नियम से बाहर का क्षेत्र पहचानें।
