4.5
*contrast between the stability of long run relative frequency and the variation of observations based on small samples
4.75
*use of random numbers to assist in probability simulations and the arithmetic manipulation of random numbers to achieve
the desired set of outcomes
4.75
*calculation of theoretical probability using ratio of number of ‘successful’ outcomes to total number of outcomes
4.75
*use of tree diagrams to explore the outcomes from multiple event trials
5.0
*Students use appropriate technology to generate random numbers in the conduct of simple simulations.
5.0
*Students identify empirical probability as long-run relative frequency.
5.0
*They calculate theoretical probabilities by dividing the number of possible successful outcomes by the total number of
possible outcomes.
5.0
*They use tree diagrams to investigate the probability of outcomes in simple multiple event trials.
Structure
5.0
*students identify collections of numbers as subsets of natural numbers, integers, rational numbers and real numbers.
5.0
They use venn diagrams and tree diagrams to show the relationships of intersection, union, inclusion (subset) and
complement between the sets.
5.0
They list the elements of the set of all subsets (power set) of a given finite set and comprehend the partial-order relationship
between these subsets with respect to inclusion (for example, given the set { a, b, c} the corresponding power set is {Ø, {a},
{b}, {c}, {a, b}, {b, c}, {a, c}, {a, b, c}}.)

Tree Diagrams
Tree Diagrams
Examine the use of tree diagrams here –
instruct students to always place the
probability on each branch in fraction
form.
Explore with replacement first.
For enrichment discuss with the students
what would change if the item was not
replaced.

*Reading Venn Diagrams
*Finding Probabilities from Venn

Human Venn Diagram
Draw or place rope in two or
three intersecting circles on the
floor. Get the students to stand
in the circle or section that they
belong in. For example the
three circles could represent 3
sports or TV programs or
Lunchbox foods.
Discuss the probabilities
represented by the diagram.
Discuss the number and how
people can belong to one or
more groups and are not
counted more than once.
