The concept of probability lines and their application in various fields such as weather predictions and transport safety is explored. The importance of students discussing and justifying their ratings on these lines is highlighted, emphasising the practical use of this mathematical tool.

What is a probability line?
A probability line is a visual representation used to assess the likelihood of an event occurring. It helps in understanding the concept of probability by placing different events along a line based on their probability, ranging from impossible to certain.

What are some examples of events that can be placed on a probability line?
Events that can be placed on a probability line can vary widely. For example, the likelihood of rain tomorrow, the chances of the Australian cricket team winning the next test match, or even the sighting of a Tasmanian Tiger. The events can be real or hypothetical, and the probability line helps in assessing their likelihood.

How can a probability line be used in the classroom?
A probability line can be used in the classroom to engage students in activities related to probability. It can be incorporated into various units of work, such as transport, the solar system, or even the likelihood of life on other planets. Students can rate different statements or events on the probability line and discuss their reasoning.

How can probability lines be integrated into different subjects?
Probability lines can be integrated into different subjects by aligning them with the content being taught. For example, in a math class, probability lines can be used to assess the likelihood of different outcomes in a game or experiment. In a science class, probability lines can be used to discuss the likelihood of certain scientific phenomena or events.
