Question

If the total area of a dartboard is 30,000 mm2 and the area of the bull's-eye is 1000 mm2, what is the probability of getting a bull's-eye?
A. 6%
B. 3%
C. 33%
D. 25%

Answer 1

Answer:

The correct option is B.

Step-by-step explanation:

It is given that the total area of a dartboard is 30,000 mm² and the area of the bull's-eye is 1000 mm².

The probability of getting a bull's-eye is

$\text{Probability of getting a bull's-eye}=\frac{\text{Area of the bull's-eye}}{\text{Total area}}$

$\text{Probability of getting a bull's-eye}=\frac{1000}{30000}$

$\text{Probability of getting a bull's-eye}=\frac{1}{30}$

$\text{Probability of getting a bull's-eye}=0.0333\approx 3\%$

Therefore the correct option is B.

Answer 2

Chances of hitting bull's-eye is $\frac{1000}{30,000}$ that =$\frac{1}{30}$ 1-:30= 0.03= 3%
