Question
Answer 4
The picture shows a fair spinner.
Look at the key words below:-
Even chance Impossible Likely Certain Unlikely
Next to each of the following sentences write the key word which describes the probability
Getting a 6……………………………………………………….
Getting a number less than 6……………………………
Getting a 1………………………………………………………….
Getting either a 3 a 4 or 5 …………………………
Which key word haven’t you used? Why?

5. Level Question Answer 5c 5b 5a In a packet of Skittles there are:-
5 red
4 blue
3 green
2 orange
6 yellow
Ben chooses a Skittle without looking. What is the Probability that Ben chooses a red skittle? Write your answer as a decimal a fraction or a percentage. 5b
True or False ?
When rolling a fair die, the probability of getting a six is greater than the probability of getting a one.
Explain your answer. 5a
True or False?
When you flip a coin, the probability of getting a head is 0.5. So if you spin a coin ten times you would get exactly 5 heads.

Probability Skills
I can use the probability words impossible, certain and even chance to describe the probability of an event occurring.
I can use the language of probability to describe the probability of an event occurring.
I can describe the probability of an event happening using a fraction, decimal or percentage.
I can list all the possible outcomes to calculate probabilities. I can complete a sample space diagram and use it to calculate probabilities.
I understand the difference between experimental and theoretical probability. I can use relative frequency as an estimate and to compare the outcomes of experiments.
Use the learning journey above to highlight the mathematical skills that you have now which you didn’t have at the start of the unit of work.
