设全集U={1,2,3,4,5,6,7,8},集合S={1,3,5},T={3,6},则CU(S∪T)等于______.
题型:填空题难度:一般来源:不详
设全集U={1,2,3,4,5,6,7,8},集合S={1,3,5},T={3,6},则CU(S∪T)等于______. |
答案
∵S={1,3,5},T={3,6} ∴S∪T={1,3,5,6} ∴CU(S∪T)={2,4,7,8} 故答案为:{2,4,7,8} |
举一反三
已知全集U={0,2,4,6,8,10},集合A={2,4,6},B={1},则(CUA)∪B等于( )A.{0,1,8,10} | B.{1,2,4,6} | C.{0,8,10} | D.Φ |
|
设全集U=A∪B={x∈N*|lgx<1},若A∩CUB={m|m=2n+1},n={0,1,2,3,4},则集合B=( )A.{2,4,6,8} | B.{1,3,5,7,8,9} | C.{2,4,5,6,8} | D.{1,3,5,7,9} |
|
集合A={x|x=2n,n∈N,0<n<12},B={y|y=3m,m∈N,0≤m≤8},则集合A∪B的所有元素之和为______. |
已知集合A={直线},集合B={圆},则A∩B中元素个数为( ) |
已知全集U={1,2,3,4,5},集合A={1,2,3},集合B={3,4,5},则(CUA)∩B=______. |
