For the fiscal year 2007, a tax authority audited 1.55% of individual tax rotterns with income of $100,000 or more. Suppose this percentage stays the same for the
current tax year. What is the probability that two randomly selected returns with income of $100,000 or more will be audited?

To find the area of shaded region, we can first find the respective area for the different rectangles.
The area of the larger rectangle:
(3x-4) × (2x+2)
=6x^2 -2x - 8
The area of the smaller rectangle:
(x-3)(x-6)
=x^2 - 9x + 18
We can then deduct the smaller area from the larger area to find the
(6x^2 -2x - 8) - (x^2 - 9x + 18)
= 6x^2 -2x - 8 - x^2 + 9x - 18
= 5x^2 + 7x -26
Therefore, the answer is 5x^2 + 7x -26.
Hope it helps!
