{0,1,2,3,4} {1,2,3,4} {1,2} {0}
={0,1,2,3}, ={1,2,4},则集合A.∪B.= ( ) A.{0, 1,2,3,4}B.{1,2,3,4} {1,2} {0}
={0,1,2,3}, ={0,2,4},那么A.∩(∁U.B.)等于( ) A.{1}B.{0,1} {1,3} {0,1,2,3}
={0,1,2,3}, ={1,2,4},则集合AB= ( ) A.{0,1,2,3,4}B.{1,2,3,4} {1,2} {0}
{1,2,4} {2,3,4} {0,2,4} {0,2,3}
{0,1,2,3} {5} {1,2,4} {0,4,5}
到集合 的一一映射,若A.={1,2,4},则A.∩B.等于( ) A.{1} B.{2} {1,2} {1,4}
={1,2,4},集合 ={3,6},则∁U.(A.∪B.)=( ) A.{1,2,4}B.{1,2,4,5} {2,4} {5}
{1,2,4} {2,3,4} {1,2} {1,2,3,4}
{1,2,3,4,5} {1,4} {1,2,4} {3,5}
{0,1,2,3} {0,4,5} {1,2,4} {4,5}
{0,1,2} {2,3} {0,1,2,3}
{1,2,3} {1,3,4} {1,2,4} {2,3,5}
={3,a2},集合 ={0,b,1-a},且A.∩B.={1},则A.∪B.=( ) A.{0,1,3}B.{1,2,4} {0,1,2,3} {0,1,2,3,4}
={0,1},则满足条件A.∪ ={0,1,2,3}的集合B.共有( ) A.1个 B.2个 3个 4个
={0,1,2,3},B={1,2,4},则集合A.∪ = A.{0,1,2,3,4} B.{1,2,3,4} {1,2} {0}
{0,1,2,3,4} {1,2,3,4} {1,2} {0}
