यदि \(U=\{1,2,3,4,5\}\), \(A=\{1,2\}\), और \(B=\{2,3,4\}\), तो (n(P(\(A\cap B\)'))) क्या है?
If \(U=\{1,2,3,4,5\}\), \(A=\{1,2\}\), and \(B=\{2,3,4\}\), then what is (n(P(\(A\cap B\)')))?
Explanation opens after your attempt
B. (16)
Concept
\(A\cap B={2}\), so (\(A\cap B\)'={1,3,4,5}). Its power set has \(2^4=16\) elements.
Why this answer is correct
The correct answer is B. (16). \(A\cap B={2}\), so (\(A\cap B\)'={1,3,4,5}). Its power set has \(2^4=16\) elements.
Exam Tip
\(A\cap B={2}\), इसलिए (\(A\cap B\)'={1,3,4,5})। इसका पावर सेट \(2^4=16\) अवयवों का होगा।
