集合U={0,1,2,3,4},M={0,3,4},N={1,2,3},则CUM∩N=( )A.{0,1,2,3,4}B.{1,2,3}C.{1,2}D.{3
题型:单选题难度:简单来源:不详
集合U={0,1,2,3,4},M={0,3,4},N={1,2,3},则CUM∩N=( )A.{0,1,2,3,4} | B.{1,2,3} | C.{1,2} | D.{3} |
|
答案
∵集合U={0,1,2,3,4}, M={0,3,4},N={1,2,3}, ∴(CUM)∩N={1,2}∩{1,2,3} ={1,2}. 故选C. |
举一反三
如果全集U=R,A={x|2<x≤4},B={3,4},则A∩(C∪B)( )A.(2,3)∪(3,4) | B.(2,4) | C.(2,3)∪(3,4] | D.(2,4] |
|
设U={0,1,2,3,4},A={0,1,2,3},B={2,3,4},则(CUA)∪(CUB)=______. |
设集合A={5,(a+1)},集合B={a,b}.若A∩B={2},则A∪B=______. |
设集合A={2,lnx},B={x,y},若A∩B={0},则y的值为( ) |
若集合A={1,2,3},B={1,3,4},则A∩B的子集个数为( ) |
