यदि \(A\subseteq U\) और \(B\subseteq U\), तो (\(A\setminus B\)') किसके बराबर है?
If \(A\subseteq U\) and \(B\subseteq U\), then (\(A\setminus B\)') is equal to what?
Explanation opens after your attempt
Correct Answer
A. \(A'\cup B\)
Concept
\(A\setminus B=A\cap B'\). Its complement is (\(A\cap B'\)'=A'\cup B).
Why this answer is correct
The correct answer is A. \(A'\cup B\). \(A\setminus B=A\cap B'\). Its complement is (\(A\cap B'\)'=A'\cup B).
Exam Tip
\(A\setminus B=A\cap B'\) है। इसका पूरक (\(A\cap B'\)'=A'\cup B) होगा।
