Complement of Set A with regards to Set C = { x/x is a number from 4 to 9}
= {4,5,6,7,8,9}'C
Complement of Set B with regards to set C  = {x/x is an even number from 4 to 10}
= {2,4,6,8,10,12}

The intersection of their complements with regards to C are:
A'C intersection B'C = {4,6,8}

Hope this helps :-)
i know the answer becuase this question was teach my teacher before lang
I think the symbol ^c is the clue. What does that mean? Is it complement?
Got it! Yehey. I'll edit my answer :-)

A={10,11,12},   B={1,3,5,7,9,11}  ={11}

Incorrect:-) What we're looking for is intersection of the complements of the sets, not intersection of the elements of the sets. :-)
Let me check again. I think we disregard C? Can you help me with this one?
Got it !! Yehey, I'll edit my answer.
