यदि \(A=\{a,b,c,d\}\) और \(B=\{c,d,e\}\) है, तो (\mathcal{P}\(A\cap B\)) में कितने तत्व होंगे?
If \(A=\{a,b,c,d\}\) and \(B=\{c,d,e\}\), then how many elements are in (\mathcal{P}\(A\cap B\))?
Explanation opens after your attempt
Correct Answer
A. (4)
Concept
\(A\cap B={c,d}\) has (2) elements. Hence (\mathcal{P}\(A\cap B\)) has \(2^2=4\) elements.
Why this answer is correct
The correct answer is A. (4). \(A\cap B={c,d}\) has (2) elements. Hence (\mathcal{P}\(A\cap B\)) has \(2^2=4\) elements.
Exam Tip
\(A\cap B={c,d}\) में (2) तत्व हैं। इसलिए (\mathcal{P}\(A\cap B\)) में \(2^2=4\) तत्व होंगे।
