This is a rough diagram to represent what is happening for the story in part b.

Does the diagram resemble something which you have learnt during secondary level Maths?

For every case, we branch out to two further outcomes. This will be why the number of variations will be 2^8 - and there are no identical scenarios also so we do not have to worry.

We remove the one case where all eight notes are not tipped.
