Question

If the total area of a dartboard is 30,000 mm2 and the area of the second ring

Answer 1

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 2

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.

$Probability=\dfrac{\text{The area of the second ring }}{\text{Total area of a dartboard}}$

$Probability=\dfrac{15000}{30000}$

$Probability=0.5$

Multiply the probability by 100 to find the percentage.

$Probability=0.5\times 100$

$Probability=50$

Hence the correct option is D.
