Answer:

254/324 which is about 78.4%

Step-by-step explanation:

found area of entire square to be 18² or 324

found area of 4-quarter circles - which equals one circle with radius of 9

A = 81π which is about 70

subtracted 324 and 70 to get 254

ratio of shaded to unshaded is 254 : 324

The Probability of point to lie is in the shaded region= [tex]\frac{254.34}{324}[/tex]

What is probability ?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomeshow likely they are.

Area of square=  side x side

                        = 18 x 18

                        = 324 sq. cm.

Area of 4 quadrant =4 x  [tex]\frac{\pi r^{2} }{4}[/tex]

                                = [tex]3.14 * 9 * 9}[/tex]

                                = 254.34 sq. cm.

So, probability that it is in the shaded region= [tex]\frac{254.34}{324}[/tex]
