Let A = {x:x ϵ N}, B = {x:x=2n,n ϵ N}, C = {x:x=2n−1,n ϵ N} and , D = {x: x is a prime natural number}. Find :
(i) A∩B (ii) A∩C
(iii) A∩D (iv) B∩C
(v) B∩D (vi) C∩D
Set U={1,2,3,4,5,6,7,8,9}A={x:x ∈N,30≤x2≤70} B={x:x is a prime number<10 }Find A′,B′,(A∪B),A′∩B′,(A−B)′
If A={x:x=2n+1,nϵZ} and B={x:x=2n,nϵZ} then find A∪B.
