## What are the possible outcomes of a spin of the spinner?

There are four possible outcomes for each spin: red, blue, yellow, green.

## What is the probability of spinning a 2 on this spinner?

The probability of spinning a 2 is 2 / 8 .

**What is the probability of the spinner landing on red?**

1 in 4

The chances of landing on red are 1 in 4, or one fourth.

### What is a spinner in probability?

This probability is equal to the amount of ‘1’s divided by the total amount of numbers on the spinner. There are 8 numbers in total on the spinner. There are 3 ones on the spinner. The probability of spinning a ‘1’ is 3 / 8 .

### How do you know if a spinner is fair?

If the spinner was fair, how many times would you expect to see each number if you spun it 300 times? An experiment is deemed to be fair if all outcomes are equally likely; that is to say, all outcomes have an equal probability or an equal chance of occurring. For this spinner, there are 10 possible outcomes.

**What is the probability of spinning a 3 out of 8?**

There are 3 ones on the spinner. 3 out of 8 parts contain a ‘1’. The probability of spinning a 1 is 3 / 8 .

## How many different combinations are there when spinning the spinner twice?

If there are 8 possibilities for the first spin, there are 8 possibilities for the second spin. 8⋅8 gives 64 total combinations for the two spins.

## What is the probability of spinning a 2 on the spinner?

**What is the probability of the spinner landing on primary color?**

The probability of landing on each color of the spinner is always one fourth.

### Are outcomes always fair?

A probability experiment may be considered “fair” if all outcomes are equally likely, or (in some cases) if the expected value of some random variable is 0 .

### What is the probability of spinning an 8?

164

However, 8,8 is unique, so it is one out of 64 possibilities. Its probability is 164 .

**How is the probability of spinning a spinner calculated?**

The sample space is the list of all possible outcomes that the spinner can land on. We will write the probability of spinning a 1 as a fraction. This probability is equal to the amount of ‘1’s divided by the total amount of numbers on the spinner.

## What happens when two spinners are spun at the same time?

Two spinners are spun at the same time, list all possible outcomes in which the first spinner lands on an even number and the second spinner lands on any letter Which describes an event that could be modeled by this tree diagram? A six-sided number cube is rolled and a coin is flipped.

## Which is more likely to spin a 2 or a 3?

Spinning a 2 and spinning a 3 are equally likely on this spinner because there is the same probability of each outcome occurring. The probability of spinning a 5 is 1 / 8 . We have filled our sample space with the probabilities of spinning each outcome. We can check that our fractions all add up to 8 / 8 or one whole.

**Why is spinning a 1 the most likely outcome?**

We can see that spinning a 1 is the most likely outcome because it has the biggest probability of occurring. When teaching probability, a common misconception is that if something is the most likely then we will expect it to occur most of the time.
