Answer:

33.5%

Step-by-step explanation:

Area of whole dartboard

radius = 3 + (4 x 4) = 19

⇒ area of whole dartboard = [tex]\pi[/tex]19² = 361[tex]\pi[/tex]

Area of 30, 40 and 50 points zone

radius = 3 + (2 x 4) = 11

⇒ area of at least 30 points = [tex]\pi[/tex]11² = 121[tex]\pi[/tex]

Probability

probability = (121[tex]\pi[/tex] ÷ 361[tex]\pi[/tex]) x 100 = 33.5%

Answer:

Area of whole dartboard

radius = 3 + (4 x 4) = 19

⇒ area of whole dartboard = 19² = 361

Area of 30, 40 and 50 points zone

radius = 3 + (2 x 4) = 11

⇒ area of at least 30 points = 11² = 121

Probability

probability = (121 ÷ 361) x 100 = 33.5%

Therefore he has a 33.5% chance of earning at least 30 points to win the game. Following that he should except his tie. considering he has less than a 50% chance.
