Solved Exercise Problems - UNIT 1 - SETS

Exercise 1.1

1) Verify the commutative property of union and intersection of sets for the following.
A={l, m, n, o, p, q}   B= {m, n, o, r, s, t}

Solution : 
Commutative Property of Union Of Sets: A∪B=B∪A
A={l,m,n,o,p,q} B={m,n,o,r,s,t}
A∪B={l,m,n,o,p,q}∪{m,n,o,r,s,t}
A∪B={l,m,n,o,p,q,r,s,t} →1

B∪A={m,n,o,r,s,t}∪{l,m,n,o,p,q}
B∪A={m,n,o,r,s,t,l,p,q}→2
Therefore, from 1 and 2 we see that A∪B=B∪A
