So in this case the spinner A’s outcomes could either be a 1 2 or aMoreFirst it lists all the outcomes. So in this case the spinner A’s outcomes could either be a 1 2 or a 5. The next thing the probability model tells you is the probability of all the outcomes.

## What is the probability of getting a 3 on this spinner?

The probability of spinning a 3 is also 2 / 8 .

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

The probability of landing on each color of the spinner is always one fourth. In Experiment 2, the probability of rolling each number on the die is always one sixth. In both of these experiments, the outcomes are equally likely to occur.

### What is the probability of landing on a 3?

A number cube (dice) has six sides labelled 1 through 6. Hence, a fair dice has a probability of 16 to land on any predetermined number 1 through 6. Therefore, to land on 3 the probability is 16 .

### How do I calculate the probability?

Divide the number of events by the number of possible outcomes.

- Determine a single event with a single outcome.
- Identify the total number of outcomes that can occur.
- Divide the number of events by the number of possible outcomes.
- Determine each event you will calculate.
- Calculate the probability of each event.

**What is the probability of landing on each color?**

What is the theoretical probability of the spinner landing on each color? Since there is only one sector in each color (red, blue, and yellow), the probability of the spinner landing on each color is 1 over 3 1 3 .

#### What is the probability of a spinner landing on red?

1 in 4

The chances of landing on red are 1 in 4, or one fourth. This problem asked us to find some probabilities involving a spinner. Let’s look at some definitions and examples from the problem above. An experiment is a situation involving chance or probability that leads to results called outcomes.

#### What is the probability of 3 coins landing on heads?

Three flips of a fair coin Suppose you have a fair coin: this means it has a 50\% chance of landing heads up and a 50\% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5\%.

**How do you calculate outcomes?**

Divide the number of events by the number of possible outcomes. After determining the probability event and its corresponding outcomes, divide the total number of events by the total number of possible outcomes. For instance, rolling a die once and landing on a three can be considered one event.

## What is the probability of spinning a number 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 . The spinner will land on a ‘1’ three times out of every eight. The probability of the spinner landing on a number is equal to the fraction of the spinner that this number occupies.

## How many ones are there on the spinner?

There are 3 ones on the spinner. The probability of spinning a ‘1’ is 3 / 8. The spinner will land on a ‘1’ three times out of every eight. The probability of the spinner landing on a number is equal to the fraction of the spinner that this number occupies.

**What is the probability of rolling each number on the die?**

In Experiment 1 the probability of each outcome is always the same. The probability of landing on each color of the spinner is always one fourth. In Experiment 2, the probability of rolling each number on the die is always one sixth. In both of these experiments, the outcomes are equally likely to occur.

### 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.
