यदि \(A=\{1,2,3,4\}\) और सार्वत्रिक समुच्चय \(U=\{1,2,3,4,5,6\}\) है, तो (P(A')) में अवयवों की संख्या क्या होगी?

If \(A=\{1,2,3,4\}\) and the universal set is \(U=\{1,2,3,4,5,6\}\), then what is the number of elements in (P(A'))?

Correct Answer

B. (4)

Step 1

Concept

(A'=U-A={5,6}), so (n(P(A'))=22=4). In exams find the complement first.

Step 2

Why this answer is correct

The correct answer is B. (4). (A'=U-A={5,6}), so (n(P(A'))=22=4). In exams find the complement first.

Step 3

Exam Tip

(A'=U-A={5,6}), इसलिए (n(P(A'))=22=4)। परीक्षा में पहले पूरक समुच्चय निकालें।
