Exemplars (from the NaCCA curriculum)
E.g. 1 Draw a probability tree diagram for the experiment in B9.4.2.1.1, E.g. 1. Express the probabilities of the events (on their respective branches) as decimals, percentages and ratios. E.g. 2: i. Consider the experiment of drawing two Aces (in two trials) in a standard deck of cards without replacement. ii. Calculate the probability of each trial and express the probabilities of the events as decimals, percentages and ratios. E.g. 3: i. Consider the experiment of drawing an Ace and a Jack (in two trials) in a standard deck of cards without replacement. ii. Calculate the probability of each trial and express the probabilities of the events as decimals, percentages and ratios.
