1. A intersection B={2,4,5,6} intersection C={6}
2. A union B={1,2,3,4,5,6}
B intersection C={6}
A union B intersection B intersection C={6}
3. A union C={1,2,3,4,5,6,7}  intersection B union C={1,2,4,5,6,7}
The intersection is {1,2,4,5,6,7}
4. A intersection B={1,2,3,4,5,6} union B intersection C {6}
Answer is {1,2,3,4,5,6}
