已知U=R,A=[0,2],B=(1,+∞),则A∩CUB=( )A.[0,1]∪(2,+∞) | B.(-∞,2] | C.[0,2] | D.[0,1] |
|
答案
CUB=(-∝,1],所以A∩CUB=[0,1] 故选D |
举一反三
已知R为实数集,M={x|x2-2x<0},N={x|x≥1},则M∩(CRN)=______. |
设集合U={1,2,3,4,5},A={1,2,B=2,3,4},则∁U(A∪B)等于( )A.{2} | B.{5} | C.{1,2,3,4} | D.{1,3,4,5} |
|
已知集合A={1,3,m},B={3,4},A∪B={1,2,3,4},则m=______. |
若集合A={x 题型:x|-x=0},B={x|x2-1=0},C={x|x>1},则(A∩B)∪C=______. |
