5:01 Chance
Write the letter of the picture that best suits the label - from certain to impossible. Match each container to a decimal, fraction or percentage on the number line that gives the chance of choosing a red ball. Show the chances as less than or greater than half.
5:02 Chance
Match the chance labels eg impossible is 0 out of 4. Estimate chances as percentages. For each outcome listed, choose a word and a decimal from the number line that would be a good estimate of its chance of occurring.
5:02E Chance
Extension page. Estimate the chances as percentages. For each outcome listed, choose a word and a decimal from the number line above that would be a good estimate of its chance of occurring. Explain how you would arrange for someone to choose an item at random from items shown.

5:03 Describing the chances
Describe the chances of winning the dice game, or of obtaining the totals given. Use the results of the experiment, shown in the table, to find the percentage chance of tossing two drawing pins so that they land in given ways.
5:04 Ordering events
Use the scale 0 to 1 to write the probability (as a decimal) of given results occurring - Spin again, win, lose. Is it more likely that the contestant will win, or lose? Is it possible/ likely for the wheel to be spun ten times without the contestant winning or losing? Explain how. Explain fairness in given dice game.
5:04C Possible outcomes
Write the total of combinations as shown in the dice diagram. Write the number of ways that each total could be tossed, out of the 36 ways. Which total would have the most/ least chance of being tossed? Match the totals that have the same chance of being tossed. Analyse dice game. Write the total easiest/ hardest to toss. Predict the game board likely to be covered first. Order the boards and test predictions by playing.
