Answer:

Option D. 4/5

Step-by-step explanation:

we know that

The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board

step 1

Find the area of the square game board

[tex]A=b^{2}[/tex]

we have

[tex]b=20\ cm[/tex]

substitute

[tex]A=20^{2}[/tex]

[tex]A=400\ cm^{2}[/tex]

step 2

Find the probability

[tex]P=320/400[/tex]

[tex]P=0.8=8/10=4/5[/tex]

Answer:

D. 4/5
