Explanations & Calculations
- Step by step to the final Venn diagram
- Last diagram in each row is the answer to the questioned set combination.
- All diagrams before it show the way of selecting component regions of the final one.
- Refer to them with the set-notation written below them.
- They are shown just to get an understanding how to arrive at the final solution
1)
(B∪C)→(B∪C)withA→→→(B∪C)∩A
2)
- (B∩C)′→(B∩C)′withA→→→(B∩C)′∩A
3)
- (A∪B)→(A∪C)→→→(A∪B)∩(A∪C)
4)
- (A∪B)→(A∪B)′→C′→→→(A∪B)′−C=(A∪B)′∩C′
