Answer

{3, 6, 9}$ (multiples of 3 less than 12)

Here are the solutions to the questions:

1. (a) Set Theory First, let's list the elements of each set: $A = \{3, 6, 9\}$ (multiples of 3 less than 12) $B = \{5, 6, 7\}$ (integers between 4 and 8, exclusive) $C = \{4, 5, 7\}$

i) Find $A \cap B$ The intersection of A and B contains elements common to both sets. $A \cap B = \{6\}$

ii) Find $(A \cup B) \cap C$ First, find $A \cup B$ : $A \cup B =
