For all sets AAA, BBB, CCC, which of the following statements is true?
(A∪B)−C=(A−C)∩(B−C)(A \cup B) - C = (A - C) \cap (B - C)(A∪B)−C=(A−C)∩(B−C)
(A∪B)−(A∩B)=(A−B)∪(B−A)(A \cup B) - (A \cap B) = (A - B) \cup (B - A)(A∪B)−(A∩B)=(A−B)∪(B−A)
A−(B−C)=(A−B)−CA - (B - C) = (A - B) - CA−(B−C)=(A−B)−C
(A∩B)∪C=A∩(B∪C)(A \cap B) \cup C = A \cap (B \cup C)(A∩B)∪C=A∩(B∪C)
