(select all correct answers)

• {1,2,3,4,5}

• 1/5

When listing the outcomes of an event, the order of the list matters

• True

• False

The spinner is spun again.

Select all the TRUE statements:

• There are 5 outcomes

• Pink is the most likely outcome

• All outcomes are equally likely

• If I spin it 100 times, I could get No Greens at all

• If I spin 100 times, I would expect to get around 20 greens

The theoretical probability of an even happening can be written as the number of ​ (a)   over the number of ​ (b)   .

• favorable outcomes

• possible outcomes

• favorite outcomes

• worst outcomes

• total trials

A(n) (a)   ​ is one or a group of possible outcomes for a given situation.​

When I spin this spinner, the 5 outcomes are all equally likely. The following statements are TRUE, but which one justifies this fact?

• 1,2,3,4,5 are all in numerical order and equally spaced.

• There are 5 different colours.

• The pentagon has five sides.

• The spinner has rotational symmetry order 5.
