यदि (n(U)=64) और (n(A')=19) है, तो (n(A)) क्या होगा?

If (n(U)=64) and (n(A')=19), what will (n(A)) be?

Explanation opens after your attempt
Correct Answer

A. (45)

Step 1

Concept

(n(A)=n(U)-n(A')=64-19=45). If the complement count is given, subtract it from the total.

Step 2

Why this answer is correct

The correct answer is A. (45). (n(A)=n(U)-n(A')=64-19=45). If the complement count is given, subtract it from the total.

Step 3

Exam Tip

(n(A)=n(U)-n(A')=64-19=45)। पूरक की संख्या दी हो तो कुल में से घटाएं।
