设U是全集,A,B,C是U的非空子集,且满足A⊆B⊆C,写出集合∁UA,∁UB,∁UC之间的关系.
举一反三
- 设全集U={1,2,3,4,5,6,7},集合A={1,2,3},集合B={1,3,5,7}则∁uA∁uB= A: {4,5,6,7} B: {2,4,6} C: {4,6} D: {1,2,3,5,7}
- 设全集U={1,2,3,4,5},A={1,2,3},B={2,3,4},则(∁UA)∪(∁UB)=( )
- 设全集U={1,2,3,4,5,6},A={1,2,4},B={2,3,4,5}.则∁UA∩∁UB等于 A: {1,2,3,4,5} B: {6} C: {3,5} D: {2,4,6}
- 设全集U={1,2,3,4,5,6},A={1,2,4},B={2,3,4,5}.则∁UA∩∁UB等于 A: {1,2,3,4,5} B: {6} C: {3,5} D: {2,4,6}
- 全集U={0,1,3,5,6,8},集合A={1,5,8},B={2},则集合(∁UA)∪B=( )
