We will draw the Venn diagram to show the universal st U and the 3 sets A, B, C
Now we will start with the common elements of A and B
5 is the common element of A and B
1 is the common element between A and C
2, 4, and 6 are the common elements between B and C
3 is in A only
Now we can answer the question using the Venn diagram
1. A' means all the elements in U except A, then
2. B U C means all elements in B and C
3. A intersect C means common elements in A and C
4. B' all elements in U not in B
5. A U B all elements in A and B
a. (A U C}' means all elements in U except A and C
Empty set because all elements are in A and C
b. A' intersects C'
No common elements between A' and C'
c. (A intersects B)' means all elements in U except the common elements between A and B
