If the total area of a dartboard is 30,000 mm2 and the area of the second ring
is 15,000 mm2, what is the probability of landing in that second ring?

A. 30%
B. 15%
C. 20%
D. 50%

Respuesta :

Answer:

probability is 50 percent

Step-by-step explanation:

total area= 30000

area of secknd ring=15000

therefore 15000/30000 times 100

equals 50 percent

Answer:

Option D.

Step-by-step explanation:

From he given information, we get

Total area of a dartboard = 30,000 mm²

The area of the second ring = 15,000 mm²

We need to find the probability of landing in that second ring.

[tex]Probability=\dfrac{\text{The area of the second ring }}{\text{Total area of a dartboard}}[/tex]

[tex]Probability=\dfrac{15000}{30000}[/tex]

[tex]Probability=0.5[/tex]

Multiply the probability by 100 to find the percentage.

[tex]Probability=0.5\times 100[/tex]

[tex]Probability=50[/tex]

Hence the correct option is D.
