1. Level34567 Probability Skills I can use the probability words impossible, certain and even chance to describe the probability of an event occurring. I can use the language of probability to describe the probability of an event occurring. I can describe the probability of an event happening using a fraction, decimal or percentage. I can list all the possible outcomes to calculate probabilities. I can complete a sample space diagram and use it to calculate probabilities. I understand the difference between experimental and theoretical probability. I can use relative frequency as an estimate and to compare the outcomes of experiments. Teacher Version

3. Which of these words describes the probability of getting tails when you flip a coin? Certain, Even Chance, Impossible If a bag contains 13 blue counters, 4 red counters and 5 yellow counters, what is the probability of getting a blue counter? Certain, Likely, Even Chance, Unlikely, Impossible If a bag contains 13 blue counters, 4 red counters and 5 yellow counters, what is the probability of getting a blue counter? Write your answer as a fraction. A spinner and a dice are used together to generate probabilities. Draw a sample space for these outcomes. Write down the probabilities. What might be different about using theoretical probability to find the probability of obtaining a 6 when you roll a dice, and using experimental probability for the same purpose?
