# Mathematics K–10 - Life Skills - Statistics and Probability Chance

## Chance: Language of Chance

### Outcomes

#### A student:

• MALS-1WM

responds to and uses mathematical language to demonstrate understanding

• MALS-3WM

uses reasoning to recognise mathematical relationships

• MALS-38SP

recognises and uses the language of chance in a range of contexts

Related Stage 4/5 outcomes: MA4-21SP, MA5.1-13SP, MA5.2-16SP, MA5.2-17SP

### Content

• Students:
• distinguish between events that are certain and events that are uncertain, eg having a birthday, winning a lottery
• describe the likelihood of familiar events using informal terms, eg might, certain, probable, likely, unlikely, possible, impossible
• predict possible outcomes in everyday situations, eg decide what might occur in a movie before the ending of the story (Communicating, Reasoning)
• ask questions related to the likelihood of events, eg 'Do I need to take my umbrella if the sky is grey?' (Communicating, Reasoning)
• use the language of chance in everyday situations (Communicating, Understanding)
• order events from least likely to most likely

## Chance: Chance and Probability

### Outcomes

#### A student:

• MALS-1WM

responds to and uses mathematical language to demonstrate understanding

• MALS-2WM

applies mathematical strategies to solve problems

• MALS-3WM

uses reasoning to recognise mathematical relationships

• MALS-39SP

recognises the elements of chance and probability in everyday events

Related Stage 4/5 outcomes: MA4-21SP, MA5.1-13SP, MA5.2-16SP, MA5.2-17SP

### Content

• Students:
• recognise the element of chance in familiar events, eg tossing a coin, rolling dice
• interpret numerical values assigned to the probability of events occurring in real-life contexts, eg 50:50, 1 in 2, 1 in 100, 1 in a million
• evaluate the probability of winning prizes in lotteries and other competitions, using online applications as appropriate (Communicating, Reasoning)
• conduct simple experiments to determine the probability of an outcome, eg spin a spinner 20 times and predict, record and communicate the results
