CIE A Level Maths: Probability & Statistics 1复习笔记2.3.2 Further Tree Diagrams
Further Tree Diagrams
What do you mean by further tree diagrams?
- The tree diagrams used here are no more complicated than those in the first Tree Diagrams revision note, however
more detailed use of conditional probability- three events for each experiment and three experiments could be used
How do I solve conditional probability problems using tree diagrams?
- The diagram above gives rise to some probability formulae you will see in Probability Formulae
Worked Example
Exam Tip
- Be wary of assuming that “given that” statements will always be referring to something on the second set of branches (2nd experiment), they can work the other way!
