  Why is it that (ii) is the best answer here. Should I be thinking that because this is a subcase of a given box dimension 1x2 , I need to keep the dimension fixed and consider the subcases ? Because to me at least (i) seems correct as well.

  Hi,

  I have a question about a) the subset in general and b) the explanation for question 20. What does a subset mean? In addition, the explanation came up with three possibilities, and I don't quite understand them (like 'in A and B', 'B but not A'.)

  Actually, never mind. I just realized that Prof. Loh just explained it in the next part.

  Hi! I don't understand why it's 6 gold pirates and not 7 if there are 7 numbers on the number line...? It's not like the separators a, b, and c will be placed between the numbers, or will they? But I do understand why it's 4 pirates. Thanks!
