This app works as a kickstarter for the full standalone "Calculating Probabilities By Using Tree Diagrams" web project. Comes packaged with all the files of the web project. (see current version for ...

Types of Tree Diagrams There are many different types of tree diagrams, including probability trees, each of which serves a different purpose. Here are some of the most common types of tree diagrams: ...

We can use the OR rule to calculate the probability: P (1 red and 1 blue) = 9 56 + 20 56 = 29 56 Often we use tree diagrams to model conditional probability.

In National 5 Lifeskills Maths explore decision-making by recognising trends and relationships and use these to state the probability of an event happening.
