यदि (n(U)=38) और (n(A)=16), तो (n(A')) क्या होगा?

If (n(U)=38) and (n(A)=16), what will (n(A')) be?

Explanation opens after your attempt
Correct Answer

B. (22)

Step 1

Concept

(n(A')=n(U)-n(A)=38-16=22). Complement is always found by subtracting from (U).

Step 2

Why this answer is correct

The correct answer is B. (22). (n(A')=n(U)-n(A)=38-16=22). Complement is always found by subtracting from (U).

Step 3

Exam Tip

(n(A')=n(U)-n(A)=38-16=22)। पूरक हमेशा (U) से घटाकर निकाला जाता है।
