S1 Oct 2025 Q8 Explained P84842A WST01 01 Edexcel Statistics

In this video, I solve Question 8 from the Edexcel International A Level Statistics 1 October 2025 paper WST01/01.

This question covers:

* Tree diagrams
* Total probability
* Conditional probability
* Probability of being late
* Completing a probability tree diagram

Final key results:

* P(\text{late})=\frac{2}{15}
* P(\text{car}\mid\text{late})=\frac{3}{4}
* Remaining tree diagram probabilities are found using conditional probability and complements

This is a clear step-by-step solution for S1 2025 October Q8, helping students understand tree diagrams and conditional probability for Edexcel IAL Statistics 1 WST01.
