Given the universal set: {−7,−3,−1,0,5,6,8,9}, B={x:−3<x<8}
⇒B={−1,0,5,6}
⇒B′={−7,−3,8,9}
Given the universal set = {−7,−3,−1,0,5,6,8,9}, find :
Given the universal set = Universal ~set = {x:x∈ N and x<20} ~find:
(i) A = {x:x=3p;p∈ N }
(ii) B = {y:y=2n+3,n∈ N }
(iii) C = {x:x is divisible by 4}
Given the universal set = {−7,−3,−1,0,5,6,8,9},A={x:x<2} then A′ is
