8 lessons of 4 planned

Use the language of probability and the probability scale

Apply the vocabulary of probability to scenarios and label the probability scale with words and numbers.

Calculate probabilities from equally likely events

Find the probability of a single, equally likely event using fractions, in a range of contexts including spinners, dice and counters. Learn how to use probability notation correctly.

Find the probability of an event not happening including using a table (include mutually exclusive and exhaustive)

Look at equally likely events and mutually exclusive events and discover the sum of probabilities to aid finding the probability of an event not happening.

Find the predicted number of outcomes

Understand the definitions of outcome, event and trial. Calculate predicted outcomes based on the results of a trial or experiment.

List outcomes in a sample space diagram (two-way table) and calculate probabilities

Learn how to construct and interpret sample space diagrams (two-way tables) including calculating probabilities, for a variety of contexts.

Calculate experimental probabilities and make predictions (relative frequency)

Learn how to record data in a relative frequency table and use the probabilities to make predictions, including scenarios such as spinners or rolling dice.

Find probabilities from Venn diagrams including basic set notation

Calculate probabilities from Venn diagrams with 2 or more sets, including using the correct notation for union, intersect and complement. It is useful to have a knowledge of how to draw Venn diagrams prior to this lesson but this skill is revised.

Find probabilities from frequency trees

Use frequency trees to find probabilities including revision on how to draw frequency trees given some information.
