Okay so we have a total of n=10 books and we want to choose 4 of them to bring with us. Order does not matter (it doesn't matter what order you picked the books, only that you picked them) so we are dealing with combinations . Therefore there are
10C4 different sets. This can be simplified using the combinations formula, but I will leave that part up to you:)
Let me know if you are still unsure.
