# reSolve: Mathematical modelling – How risky is life?

In this unit of work, students explore the risks of dying unexpectedly from various causes. They start from their own fears and, by comparing them with Australian Bureau of Statistics data, recognise that these are often unfounded and sometimes driven by the media. Students learn how to calculate the risks involved for various activities and how these are related to the base risk of death for people of different ages and genders. The emphasis is on order-of-magnitude comparisons, reflecting the various kinds of variation in risk level between individuals and over time.
