This sketch contains comedy cartoon violence. Show how probability is linked to being able to predict outcomes and their likelihood. For different levels of students this can be linked to simple actions such as coin or dice tossing or more complex processes involving conditional probability. Discuss the law of large numbers in relation to statistics and experimentation and explore how sample size is related to accuracy. Relate probability to aspects of financial education, exploring the concept of risk, how risk can be calculated and its impact on the size and security of returns.
