Lesson

What outcomes can happen when you roll a die? Can you make a list? Which outcomes are odd? Which outcomes are even?

A six-sided die is rolled.

a

List all the possible outcomes from rolling the die:

⬚, \,2, \,⬚, \,⬚, \,5, \,6

Worked Solution

b

What is the chance that a 6 is rolled?

A

Likely

B

Unlikely

Worked Solution

Idea summary

A six sided die has 1, 2, 3, 4, 5, and a 6 on it only. So those numbers are the only possible outcomes when rolling a die.

Sometimes there are events that can have an impact on others. This video shows us what this means.

If the following spinner is spun and lands on a star twice in a row, will this affect the chance of the spinner landing on a star on the third spin?

Worked Solution

Idea summary

The outcome of a spinner gives random results. This means the previous spin will not affect the result of the next spin.

Some types of experiments mean that only one outcome can happen in each trial. This video shows us what this means.

A coin is tossed. Is it possible for the following two outcomes to happen at the same time?

The coin lands on heads

The coin lands on tails

Worked Solution

Idea summary

Flipping a coin will always give one possible outcome:

The coin lands on heads

The coin lands on tails

Sometimes in an experiment, there are multiple things that could happen as an outcome. For example, if you roll a die then you could get a 3, and an odd number at the same time. This video shows us more about this.

A dog is randomly selected from the group of dogs shown.

Which two outcomes could happen at the same time?

A

Selecting a dog that is running

B

Selecting a dog with something in its mouth

C

Selecting a dog with its tongue out

D

Selecting a dog with spots

Worked Solution

Idea summary

Sometimes, the result of an experiment can impact the outcome of the next result. Other times, it doesn't matter what the outcome is, it doesn't have any impact on other results.

Identify everyday events where one cannot happen if the other happens

Identify events where the chance of one will not be affected by the occurrence of the other
