Timed!
a three-section spinner, is spun twice. the tree diagram shows the possible outcomes for the two spins.
what is the probability of spinning the same number in both spins?
a) 1/9
b) 1/6
c) 1/3
d) 1/2

Option C

Step-by-step explanation:

We have a three section spinner and we want to know what is the probability of spinning the spinner twice and getting the same number.

The tree diagram shows that by spinning the spinner 2 times there are 9 possible results

Note that among these 9 possible outcomes there are 3 ways to get the same number

Then the definition of probability tells us that:

In this case

Finally
