Question

Find the following sets:
(L U M)'
L= {2,4,6,8,10}
M= {1,4,8,12}

Answer 1

What is the universe set?

Answer 2

the inside part L U M can be found by writing a set that contains all the elements from both L and M (no need to write an element twice)
but (L U M)' means all the elements in the universe that aren't in L U M

Answer 3

universe={1,2,3,4,5}
for example L={2} and M={3}
then L U M={2,3}
and (L U M)'={1,4,5}
