已知全集U={0,1,2,3,4},集合A={0,1,2,3},B={2,3,4},那么CU(A∩B)( )A.{0,1} | B.{2,3} | C.{0,1,4} | D.{0,1,2,3,4} |
|
答案
∵集合A={0,1,2,3},B={2,3,4}, ∴A∩B={2,3}, 又全集U={0,1,2,3,4}, 则CU(A∩B)={O,1,4}. 故选:C. |
举一反三
已知集合M满足M∪{1,2}={1,2,3},则集合M的个数是( ) |
设全集U={1,2,3,4,5,6,7},∁U(A∪B)={1,3},A∩(∁UB)={2,5}.则集合B=( )A.{4,6,7} | B.{1,2,3,5} | C.{2,4,6} | D.{1,3,5} |
