यदि \(U={1,2,\ldots,40}\), (A) अभाज्य संख्याओं का और (B) सम संख्याओं का समुच्चय है, तो \(A\cap B\) क्या है?
If \(U={1,2,\ldots,40}\), (A) is the set of prime numbers and (B) is the set of even numbers, then what is \(A\cap B\)?
Explanation opens after your attempt
Correct Answer
A. ({2})
Concept
The only even prime is (2), so \(A\cap B={2}\). In an intersection, both conditions must be satisfied together.
Why this answer is correct
The correct answer is A. ({2}). The only even prime is (2), so \(A\cap B={2}\). In an intersection, both conditions must be satisfied together.
Exam Tip
सम अभाज्य संख्या केवल (2) है, इसलिए \(A\cap B={2}\) है। प्रतिच्छेद में दोनों शर्तें साथ में पूरी होनी चाहिए।
