Answer:
Step-by-step explanation:
we know that
The probability that a point in the square below is in the shaded region, is equal to divide the area of the shaded region by the area of the square
step 1
Find the area of the shaded region
The area is equal to the area of the square minus the area of the circle
we have
---> length side of the square
----> the radius is half the diameter
assume
substitute
step 2
Find the area of the square
we have
---> length side of the square
substitute
step 3
Find the probability
