已知全集U={0,1,2,3,4,5,6,7,8,9},集合A={0,1,3,5,8},集合B={2,4,5,6,8},则(CUA)∩(CUB)=(  )
A.{5,8}B.{7,9}C.{0,1,3}D.{2,4,6}
答案
由题义知,全集U={0,1,2,3,4,5,6,7,8,9},集合A={0,1,3,5,8},集合B={2,4,5,6,8},
所以CUA={2,4,6,7,9},CUB={0,1,3,7,9},
所以(CUA)∩(CUB)={7,9}
故选B
举一反三
设集合U={1,2,3,4},A={2,3},B={1},则A∩(CUB)等于(  )
A.{2}B.{3}C.φD.{2,3}
