The diagrams illustrate Venn diagrams.
In (a), the two sets $A$ and $B$ overlap within the universal set.
In (b), the elements are arranged as follows:
In $X$ only: $a, h, f$
In $X \cap Y$: $c, s, d$
In $Y$ only: $p, b, g$
Outside both sets: $m, e$.
(a)[1]
Use set notation to state the shaded part of the Venn diagram.
(b(i))[1]
Give the elements of set $Y$.
(b(ii))[1]
State $n(X \cup Y)$.
