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

chances of hitting bull's-eye is
`(1000)/(30,000)` that =
`(1)/(30)` 1-:30= 0.03= 3%

Answer 2

The correct option is B.

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}=(1000)/(30000)`

`\text{Probability of getting a bull's-eye}=(1)/(30)`

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

Therefore the correct option is B.
