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

Verified Answer :

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

Answer: C. \(\dfrac{4}{25}\)

Step-by-step 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 =\(\dfrac{\text{Numbers greater than 6}}{\text{Total numbers}}\)

\(=\dfrac{4}{10}\)

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

\(\dfrac{4}{10}\]times\dfrac{4}{10}=\dfrac{4}{25}\)

Hence, the correct answer is Option C. \(\dfrac{4}{25}\)
