यदि \(U={1,2,\ldots,16}\), \(A=\{1,2,4,8,16\}\) और \(B=\{2,4,6,8,10,12,14,16\}\), तो (B-A) किसके बराबर है?
If \(U={1,2,\ldots,16}\), \(A=\{1,2,4,8,16\}\) and \(B=\{2,4,6,8,10,12,14,16\}\), what is (B-A) equal to?
Explanation opens after your attempt
Correct Answer
A. \(B\cap A'\)
Concept
The difference (B-A) means in (B) and not in (A), that is \(B\cap A'\). Writing difference with complement is easier.
Why this answer is correct
The correct answer is A. \(B\cap A'\). The difference (B-A) means in (B) and not in (A), that is \(B\cap A'\). Writing difference with complement is easier.
Exam Tip
समुच्चय अंतर (B-A) का अर्थ है (B) में और (A) में नहीं, यानी \(B\cap A'\)। अंतर को पूरक से लिखना आसान है।
