题目内容
【题目】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(UA)∩(UB)=( )
A.{5,8}
B.{7,9}
C.{0,1,3}
D.{2,4,6}
【答案】B
【解析】解: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
由题已知全集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},可先求出两集合A,B的补集,再由交的运算求出(UA)∩(UB)
