Question

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

Answer 1

78.5%

Explanation:

Let radius of each circle=r

then, length of square=4r

Then, Area of shaded region=Area of 4 circles=4×πr²

= 4×3.14×r²

= 12.56×r²

Now, total area of figure= area of square

= 4r×4r

= 16×r²

Hence, probability that point will be in shaded region

= area of shaded region/total area of figure

= 12.56/16

=0.785

≈ 78.5%

Hence, no option is correct

Answer 2

a - side of a square

r - radius of a circle
