Mathematics / Year 9 / Probability

Curriculum content descriptions

list all outcomes for compound events both with and without replacement, using lists, tree diagrams, tables or arrays; assign probabilities to outcomes (AC9M9P01)

Elaborations
  • discussing two-step chance experiments, such as the game of Heads and Tails, describing the different outcomes and their related probabilities
  • using systematic methods such as lists or arrays to record outcomes and assign probabilities, such as drawing the names of students from a bag to appoint \(2\) team leaders
  • using a tree diagram to represent a three-stage event and assigning probabilities to these events; for example, selecting \(3\) cards from a deck, assigning the probability of drawing an ace, then a king, then a queen of the same suit, with and without replacing the cards after every draw
  • assigning probabilities to compound events involving the random selection of people from a given population; for example, selecting \(2\) names at random from all of the students at a high school and assigning the probability that they are both in Year 9
General capabilities

ReSolve: Hot Streaks

This sequence of two lessons students investigate streaks in statistical data. They develop tests for randomness in order to distinguish between random and non-random results and use their understanding of randomness to investigate the existence or otherwise of the 'hot streak' phenomenon in basketball. Each lesson is outlined ...
