You can put this solution on YOUR website! Given universal set U= {10,20,30,40,50,60,70,80,90}
with subsets A= {20,40,60,80} and B= {30,60,90},
find A ∩ B
Substitute the sets for the letters:
A ∩ B
{20,40,60,80} ∩ {30,60,90}
The symbol ∩ is for intersection, which means to
make a set that contains only the elements which
are common to both sets. So the answer is
{60}
That's because 60 is the only element in common
to both sets.
