Exemplars (from the NaCCA curriculum)
Encourage learners to use their communication skills, combined problem-solving competencies and critical thinking skills to discuss the role of probability in society by applying probability reasoning to investigate and make useful guesses about everyday life events and use them to make judgements and suitable decisions in their everyday activities. Group discussions: In small groups, task learners to list and present with an explanation, at plenary, some decisions that point to uncertainties/certainties of everyday life. Examples: i. Going out with or without an umbrella, the safety of crossing a road, the chance of dying in an accident on a particular stretch of a road/highway, and so on. ii. Before planning for a picnic, you check the weather forecast, and it says there is a 60% chance (probability) that rain may occur. Discuss and provide answers to the following questions: a) What does this probability mean? b) How was the 60% determined? c) What are the things taken for granted in determining the probability (assumptions) and/or anything that could change the forecast (limitations), if any? d) How will it influence your decision on the planned picnic? iii. Discuss and provide answers to the following questions. (Interpret and explain the answers, indicating the assumptions and limitations involved, if any. (Refer to E.g., 2) a) How do political analysts predict a certain political party to come into power? b) Flipping a coin is one of the most important events before the start of a football match. What is the chance or the probability of your team getting the desired outcome? c) As an active smoker, the chances (probability) of getting lung disease are higher in you. Aware of this fact, which insurance scheme will you go for health, vehicle or house insurance? d) Nowadays, people are using mobile phones, and the chances of their mobile phones getting damaged or lost are high. Do you think they should consider getting insurance for their expensive mobile phones?
