One of my students told me a similar vector question came out in this year’s A level P2.
Luckily we went through this question one day before the paper. Yeah!

An alternative method to solve the question is also provided.

Many students have problems with solving part (iii) of the question.
It is easier to solve with the aid of a Venn Diagram. Once the required region is identified, think of the possible events that can occur within that region, and come out with the required probabilities. If you are still having problems, whatsapp me! 🙂
