3. A = Set of deck of cards
B = Set of English alphabet
C = Set of vowels
4. WAYS TO DESCRIBE A SET :
1.ROSTER/ TABULAR METHOD
- the elements in the given set are listed or enumerated,
separated by a comma, inside a pair of braces.
2. RULE/ DESCRIPTIVE METHOD
- the common characteristic of the elements are defined.
- the elements are not listed but are indicated by
description of their characteristics.

Answer the following questions .
24. In the diagram below, there are two sets, A = {1, 5, 6, 7, 8, 9, 10, 12}
and B = {2, 3, 4, 6, 7, 9, 11, 12, 13}. The section where the two sets
overlap has the numbers contained in both Set A and B, referred to as
the intersection of A and B. The two sets put together, gives their
union which comprises of all the objects in A, B which are {1 2 3 4 5 6
7 8 9 10 11 12 13}.
A intersect B
{ 6, 7, 9,12 }
A union B
{ 1,8,5,10,6,7,9,12,,3,4,2,13,11 }
