These are the Transum resources related to the statement: "Understand and use conditional probability, including the use of tree diagrams, Venn diagrams, two-way tables. Understand and use the conditional probability formula P(A|B)=P(A∩B)/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.
- Set Notation Matching Match the set notation statements with the equivalent symbol. A drag and drop self-marking exercise.
- Tree Diagrams Calculate the probability of independent and dependent combined events using tree diagrams.
- 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 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.

Here are some exam-style questions on this statement:

- "
*A driving test has two sections, practical(p) and theory(t). One day everyone who took the test passed at least one section. 77% passed the practical section and 81% passed the theory section.*" ... more - "
*The Venn diagram represents a collection of 40 books on sale in an online store.*" ... more - "
*Twenty nine children went to a zoo to photograph some animals. The numbers of children who photographed Lions(L), Monkeys(M) and Zebras (Z) are given as follows:*" ... more - "
*Neal is attending a Scout jamboree in Japan. He has both boots and trainers to wear. He also has the choice of wearing a cap or not.*" ... more - "
*Let A and B be events such that \(P (A) = 0.45\) , \(P (B) = 0.35\) and \(P (A \cup B) = 0.5\).*" ... more - "
*The Venn diagram below shows the events \(A\) and \(B\), and the probabilities p, q and r.*" ... more - "
*Julie chooses a cake from a yellow box on a shelf. The box contains two chocolate cakes and three plain cakes. She eats the cake and chooses another one from the box. The tree diagram below represents the situation with the four possible outcomes where C stands for chocolate cake and P for plain cake.*" ... more - "
*Jane and David play two games of golf. The probability that Jane wins the first game is \(\frac56\). If Jane wins the first game, the probability that she wins the second game is \(\frac67\).*" ... more - "
*Two events A and B are such that \(P(A) = 0.57\) and \(P (A \cap B) = 0.21\).*" ... more
