Difference of two squares.
a^2 - b^2 = (a+b)(a-b)
remember this as you will incur it a lot in all of algebra up through calculus.....
Given:
A grid with a shaded region.
To find:
The probability that a point chosen at random on the grid will lie in the shaded region.
Solution:
We have,
Total number of small boxes = 100
Number of blue boxes (shaded region) = 36
Now,
probability that a point chosen at random on the grid will lie in the shaded region is
![\text{Probability}=\dfrac{\text{Number of blue boxes (shaded region)}}{\text{Total number of small boxes}}](https://tex.z-dn.net/?f=%5Ctext%7BProbability%7D%3D%5Cdfrac%7B%5Ctext%7BNumber%20of%20blue%20boxes%20%28shaded%20region%29%7D%7D%7B%5Ctext%7BTotal%20number%20of%20small%20boxes%7D%7D)
![\text{Probability}=\dfrac{36}{100}](https://tex.z-dn.net/?f=%5Ctext%7BProbability%7D%3D%5Cdfrac%7B36%7D%7B100%7D)
To find the probability in percent, multiply it by 100.
![\text{Probability}\%=\dfrac{36}{100}\times 100](https://tex.z-dn.net/?f=%5Ctext%7BProbability%7D%5C%25%3D%5Cdfrac%7B36%7D%7B100%7D%5Ctimes%20100)
![\text{Probability}\%=36\%](https://tex.z-dn.net/?f=%5Ctext%7BProbability%7D%5C%25%3D36%5C%25)
Therefore, the correct option is A.
