Question

June spun a spinner that is evenly spaced and numbered from 1 to 10. When it stopped, June spun it again. What is the probability that the spinner stopped on a number greater than 6 on both spins?

A.1/4
B.2/5
C.4.25
D.4/5

Answer 1

c it's 4.25 because if it was 5 or higher it would be a 1/2

Answer 2

Answer: C.
`(4)/(25)`

Explanation:

Given : A spinner that is evenly spaced and numbered from 1 to 10. When it stopped, June spun it again.

Then both events of spinning the spinner is independent of each other.

The numbers greater than 6 on spinner = 7 , 8, 9, 10

Probability of getting a number greater than 6 on one spin =
`\frac{\text{Numbers greater than 6}}{\text{Total numbers}}`

`=(4)/(10)`

Since , both vents are independent , then probability that the spinner stopped on a number greater than 6 on both spins will be :-

`(4)/(10)\]times(4)/(10)=(4)/(25)`

Hence, the correct answer is Option C.
`(4)/(25)`
