the union of two is sets, is a set with the elements that appear in either (or both) sets, (don't repeat any element)

anonymous · Answer

So, i cant repeat any number in the union?

unklerhaukus · Answer

that's right, any element should appear in a set, at most once

anonymous · Answer

So if i cant repeat any number, it would be {2, 7, 8} since group K only has 2 and 8, while group L only has3?

unklerhaukus · Answer

when i said dont repeat 
i mean like:

if     X={a,b,c},        Y={c,d,e}

the union would be 

X ∪ Y =  {a,b,c} ∪ {c,d,e} =  {a,b,c,d,e}   

the union is like you merge the two sets 

                                          (note that both sets have 'c' 
                                            but there is only one  'c'  in the union)
