Question

Let $A$ and $B$ be two sets in the same universal set. Then, $A-B=$

• A. $A\cap B$
• B. $A\cap B^{\prime }$
• C. None of these
• D. $A^{\prime }\cap B$

Answer 1

The correct option is B $A\cap B^{\prime }$

Let U be the universal set of set A and set B.
We know that
$A-B$ have elements which belong to set A but do not belong to set B.
Therefore,
$A-B=A\cap B^{\prime }$
Thus, the correct answer is option (C).
