10 \(\mathscr{E} = \{2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13\}\)
\(A = \{2, 4, 6, 8, 10, 12\}\)
\(B = \{3, 6, 9, 12\}\)
(a) List the members of the set \(A \cup B\) (1)
\(C\) is a set with 4 members.

Notes
B2: (B1 any set of 4 elements which satisfies exactly one of \(A \cap C = \varnothing\), \(B \cap C = \varnothing\) or just 2 or 3 of 5, 7, 11, 13 or all four correct values and one incorrect value eg 1, 5, 7, 11, 13)
