Respuesta :

Answer:

E. 0.2146

Step-by-step explanation:

Area of the Square =10 X 10=100 Square cm

Area of the Shaded Region=Area of Square-Area of Circle

[tex]=10^2-\pi *5^2\\=21.46cm^2[/tex]

Therefore, the probability that the point K lies in the shaded region is:

[tex]=\dfrac{\text{Area of the Shaded Region}}{\text{Total Area}} \\=\dfrac{21.46}{100}\\\\=0.2146[/tex]

The correct option is E
