Question

Let $A$ and $B$ be subsets of a set $U$. Identify the given statement is right or wrong:
$A△B=B△A$

Answer 1

• $A$ and $B$ subset of $U$.

$A\Delta B=(A\cup B)-(A\cap B)$

$B\Delta A=(B\cup A)-(B\cap A)$

$A\cup B=B\cup A$

$A\cap B=B\cap A$

So,$A\Delta B=B\Delta A$

The given statement is right.
