Question

u={x:xez,-2<x<10},A={x:x=2p+1,-1<q<4}B={x:x=3q+1,qez,-1<q<4} find A', (AuB)'​

Answer 1

Step-by-step explanation:

We have, P={x: x<3,x ∈ N} = {1,2}

And Q = {x :x≤ 2,x∈ W] = {0,1,2}

P∪Q= {0, 1,2} and P ∩ Q= {1,2}

(P ∪ Q) x (P ∩ Q) = {0,1, 2} x {1,2}

= {(0,1), (0, 2), (1,1), (1,2), (2,1), (2, 2)}
