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

a - side of a square

r - radius of a circle

Hm, looks like none of the asnwers is correct.

78.5%

Step-by-step 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

probability for j is 1/4

while

a is 1/6

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
