O Level Mathematics 4024 · Probability. Calculate the probability of combined events using, where appropriate: sample space diagrams Venn diagrams tree diagrams. Combined events could be with or without replacement. The notation P(A ∩ B) and P(A ∪ B) may be used in the context of Venn diagrams. On tree diagrams outcomes will be written at the end of the branches and probabilities by the side of the branches.
