Answer
$A'\cap (T\cup W)$
6.1 million
Work Step by Step
From the table we see that the set of sales in years other than 2009 can be written in a form $A'$ and the set of sales in the West and South can be written in a form $T\cup W$
Therefore the set of sales in the West and South in years other than 2009 is $A'\cap (T\cup W)$
From the table we see that its cardinality is $1.9+1.9+1.1+1.2=6.1$ (million)
