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
To find the probability in percent, multiply it by 100.
Therefore, the correct option is A.
