Answer:
0.15
Step-by-step explanation:
Area = [tex]\pi[/tex][tex]r^{2}[/tex]
Area of the shaded region = [tex]\pi 5^{2}[/tex]
Area = 78.5 [tex]in^{2}[/tex]
Area of the whole dart board = [tex]\pi r^{2}[/tex]
Area = [tex]\pi 13^{2}[/tex]
Area = 530.66[tex]in^{2}[/tex]
Probability = [tex]\frac{78.5}{530.66}[/tex]
= 0.1479 ≈ 0.15
