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( ) |
若全集为R,集合P={x|f(x)≥0,x∈R},集合Q={x|g(x)<0,x∈R},则不等式组的解集可用P、Q表示为______. |
使集合Y={1,3}且X∪Y={1,2,3,4},同时成立的集合X有______. |
集合A={x|1<x<2},B={x|x<a},且A∪B=B,则 a范围是______. |
