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

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

the answer

b. they are parallel and will never intersect.
