Question

A spinner is divided into eight equal- sized sections. Each section is labeled with a number.

(Below is the spinner, I tried my best)

3 2

1 1

1 4

3 1

Jake spins the arrow on the spinner once. Put the events into the correct order from least likely to most likely.

The Options:

-Arrow lands on a section. 1) ______ 2)_____ 3)_____

labeled with an odd number. _{Least Likely Most likely}

-Arrow lands on a section

labeled with the number 1.

-Arrow lands on a section

labeled with a number

less than 4. _

Answer 1

-Arrow lands on an odd number: First, count how many odd numbers there are. (In this case they are 1 and 3.) There are four 1's, and two 3's. That means there are 6 odd numbers on the spinner. Next, how many numbers are there in total on the spinner? There are 8 numbers total on the spinner. So, 6 out of the 8 numbers are odd numbers. Therefore, the probability that the arrow lands on an odd number would be 6/8. That can also be simplified to 3/4 (or a 75% chance).

-Arrow lands on a section labeled with the number 1: Count how many 1's are on the spinner. There are four 1's on the spinner, and there are 8 numbers total on the spinner. So, the probability of the arrow landing on a 1 is 4/8, which can be simplified to 1/2 (50%).

-Arrow lands on a section labeled with a number less than 4: First, what numbers are less than 4? 3, 2, and 1 are less than 4. How many 3's are there? There are two 3's. How many 2's are there? There is one 2. How many 1's are there? There are four 1's. 2+1+4=7. So, 7 out of the 8 numbers are numbers that are less than 4. The probability of the arrow landing on a number less than 4 is 7/8, which is 88.5%.

So, now order the percentages from least to most, to find out the least likely to happen to the most likely to happen. The least likely is the arrow landing on a section labeled with the number 1, because the probability is 50%. Then, the arrow landing on an odd number would be next, with a probability of 75%. The most likely to happen would be the arrow landing on a section labeled with a number less than 4, with a probability of 88.5%.

Hope that helped!

Answer 2

-Arrow lands on a section.

labeled with an odd number. 6/8 Most Likely

-Arrow lands on a section

labeled with the number 1. 4/8 Even Odds

-Arrow lands on a section

labeled with a number

less than 4. 7/8 Most Likely
