Given sets A, B, C, D as shown below
Union of two sets is denoted by symbol U and it includes all the elements in both the sets.
Intersection of two sets is denoted by symbol ∩  and it includes only the elements which are common in both the sets.

A -a.g]
, e, f.
.b, c
B = [d.e.f.8]
C =[a.c.f]
D=[f.h.k]
