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

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. $\dfrac{4}{25}$

Answer 2

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