These are the Transum resources related to the statement: "Use of Venn diagrams, tree diagrams, sample space diagrams and tables of outcomes to calculate probabilities. Combined events: P(A∪B)=P(A)+P(B)-P(A∩B). Mutually exclusive events: P(A∩B)=0. Conditional probability: P(A|B)=P(A∩B)/P(B). Independent events: P(A∩B)=P(A)P(B)".

Here are some specific activities, investigations or visual aids we have picked out. Click anywhere in the grey area to access the resource.

- Probability Basic probability questions in an online exercise.
- Probability Formulae Show that you know which formula (as given in the IB Formula Booklet) to use for each probability question. A drag and drop challenge.
- Snail Race Twelve snails have a race based on the sum of two dice. This is the teachers' version of the race simulation.
- Snail Race A race between 12 snails. Which snail is most likely to win? This is the students' version of the race simulation.
- Tree Diagrams Calculate the probability of independent and dependent combined events using tree diagrams.
- Two Dice Possibility Space An interactive visual aid showing the possibility space obtained when throwing two dice
- Venn Diagram Place each of the numbers 1 to 16 on the correct regions on the Venn diagram.
- Venn Diagram Pairs The traditional pairs or pelmanism game adapted to test knowledge of Venn diagrams.
- Venn Matching Game Match the sets statement with the equivalent Venn diagram. A drag and drop self marking exercise.
- Venn Paint Flood fill the regions of the Venn diagrams according to the given statements.
- Venn Totals Practise reading and creating Venn diagrams containing two and three sets and the number of elements in those sets.
