Students are required to give reasons why the samples used to survey New Zealand school students on their favourite sports, may not be representative of the population.
Students complete a tree diagram to illustrate all the different combinations of height and colour of four candles and evaluate probabilities for some combinations.
Pairs of students play a game with four dice, calculate the probability of winning the game, comment on how to get a more accurate estimate of the probability, and explain whether the game is fair based on their results.
