MATHEMATICS 5 CURRICULUM GUIDE 2015
Specific Outcomes
PROBABILITY
Suggestions for Teaching and Learning
Students will be expected to:
Statistics and Probability (Chance and Uncertainty)
Achievement Indicators:
5SP3.2 Classify the likelihood 
of a single outcome occurring 
in a probability experiment as 
impossible, possible or certain.
Using a diagram to show the relationship between these three cases 
may be helpful for some students. They should realize that 
possible
and 
impossible 
are mutually exclusive but that 
certain
is a subset of
 possible.
Experimental probability is the probability reached by actually 
performing an experiment. In theory, for example, if you flip a coin 
two times you should get one head and one tail. However, after flipping 
the coin twice you may get two heads. The more you flip the coin, the 
greater the chance of having equal numbers of heads and tails results.
Using spinners, dice or coloured cubes, ask students to predict whether 
the outcome will be impossible, possible or certain. Examples include 
the following: 
• From a bag containing red cubes and yellow cubes:
(i) What is the likelihood of picking a yellow cube?
(ii) What is the likelihood of picking a green cube?
(iii) What is the likelihood of picking a cube which is red or yellow?
• Using the spinner shown:
(i) What is the likelihood of the spinner landing
on five?
(ii) What is the likelihood of the spinner landing
on one or two?
• When rolling a standard die:
(i) What is the likelihood that you will roll a one, two, three, four,
five or six?
(ii) What is the likelihood of rolling a seven?
