Understand relative frequency as an estimate of probability and calculate expected frequencies

Calculate probabilities of combined events using sample space (possibility) diagrams, tree diagrams and Venn diagrams, with replacement at Core and with or without replacement at Extended

Calculate conditional probabilities using Venn diagrams, tree diagrams and tables (Extended)
