Lesson 1
8A Review of Probability
Find probabilities of equally likely outcomes, use the 0-1 scale, and apply the complement.
Lesson 2
Multi-stage Events and Counting
Count outcomes and calculate probabilities for simple multi-stage events with and without replacement.
Lesson 3
Tree Diagrams
Use tree diagrams to organise stages, multiply along paths and add alternative successful paths.
Lesson 4
Venn Diagrams
Interpret Venn regions, overlaps, unions and students outside both sets.
Lesson 5
Two-way Tables
Read two-way tables, identify joint and marginal frequencies, and compare proportions.
Lesson 6
Conditional Probability
Calculate simple conditional probabilities by restricting the group represented by the denominator.
Lesson 7
8C Mutually and Non-Mutually Exclusive Events
Recognise mutually exclusive events and use the addition rule, vs overlapping and independent events.
Lesson 8
8E Arrays for Two-Step Experiments
List outcomes of two-step experiments with arrays and tree diagrams, and find probabilities.
Lesson 9
8G Dependent and Independent Events
Distinguish dependent from independent events and use the multiplication rule for 'and'.
