A point in the figure is selected at random. Find the probability that the point will be in the shaded region.

A.) about 90%
B.) about 70%
C.) about 60%
D.) about 80%

Option D - about 80% is the answer

Step-by-step explanation:

Step 1 :

Let L be the length of the square

Since the 2 semi circles are drawn with side of the square as diameter , the diameter of the 2 shaded semicircles is L

Hence the radius =  

Step 2 :

The total outcome  = the point is inside the square =  area of the square = L²

The favorable outcome is that the point is inside the shaded area  = Area of  2 shaded semi circles of radius L/2 = × =   ×

The probability that the point is inside the shaded area = favorable outcome ÷ the total outcome

  = ( × ) ÷  L² =  = = 0.785

Converting this into percentage it give 78.5% which is about 80%
