Probability trees - dependent events
Probability trees are an excellent tool for modelling dependent events,
Probability
Probability is about measuring chance and making sense of uncertain events. Students often need practice choosing the right representation, such as a probability scale, sample space, frequency tree, Venn diagram or tree diagram. These worksheets help students build confidence with both simple probability calculations and the more structured reasoning needed for combined events.
