So I firstly took the approach that you have:

Person 1: Spot1 Spot2 Spot3 Spot4

Person 2: Spot1 Spot2 Spot3 Spot4

And then filling in how many book options there are in each spot.

So Person 1 Spot1 has 4 options.

Whereas Person2 Spot1 then has only 3 options (as one book is being read).

Therefore Person 1 Spot 2 then has 3 options left (Person1 has read one book already).

My biggest issue is in Person 2 Spot 2, I think there are 3 options, but not sure! (As Person2 has read one book, so has three remaining??) (or only 2 options?)

Then Person 1 Spot 3 has 2 opitons, Person 1 Spot4 has 1.

Person 2 Spot 3 I think has 2 remaining (or 1) and Person 2 Spot 4 has 1

Sooooo I think there are

Person 1: 4 3 2 1

Person 2: 3 3 2 1

Which results in 432 different ways in which to read the books... is this right though cos I have a feeling it may be

Person 1: 4 3 2 1

Person 2: 3 2 1 1

Which means there are only 144 options?

Thanks!
