Answer
C∩(AUB)'
Work Step by Step
Our required regions are VII.
From the given Venn diagram,
Now we know that set (AUB)' represents the regions VII, VIII, and set C represents the regions IV, V, VI, VII.
The common portions for both C and (AUB)' represents the regions VII, which is our required region.
Therefore the answer is C∩(AUB)'.
