यदि \(U=\{1,2,3,4,5,6,7,8\}\) और \(A=\{1,3,5,7\}\), तो (P(A')) के कितने अवयवों में केवल सम संख्याएँ होंगी?
If \(U=\{1,2,3,4,5,6,7,8\}\) and \(A=\{1,3,5,7\}\), how many elements of (P(A')) contain only even numbers?
Explanation opens after your attempt
Correct Answer
B. (16)
Concept
(A'={2,4,6,8}), so all its subsets contain only even numbers. The number is \(2^4=16\).
Why this answer is correct
The correct answer is B. (16). (A'={2,4,6,8}), so all its subsets contain only even numbers. The number is \(2^4=16\).
Exam Tip
(A'={2,4,6,8}), इसलिए इसके सभी उपसमुच्चय केवल सम संख्याओं के होंगे। संख्या \(2^4=16\) है।
