Given the universal set U = {−7,−3,−1,5,6,8,9} and A={x:x<2}. Find (A').
Given the universal set U = {−7,−3,−1,5,6,8,9},A={x:x<2}
⇒A={−7,−3,−1} The complement of set A
⇒A′={5,6,8,9}
Given the universal set = {−7,−3,−1,0,5,6,8,9},A={x:x<2} then A′ is
Given U={x:x∈N,x≤9}, A={x:x is divisible by 2} and B={x:x3∈N}, where U is the universal set. Then, (A∪B)−(A∩B) = ____.
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}
