Answer 1

actually either 7 or 8 because i picked 6 & got it wrong

Answer 2

How many sets can you make with 3 things in it? How many sets can you make with 2 things in it? 1? 0?

Answer 3

i dont know, i could only think of
1
2
3
1,2
1,3
2,3

Answer 4

Yeah, exactly that list is right except you forgot the empty set {} and the full subset {1,2,3}. It seems like {1,2,3} isn't a subset of {1,2,3} but it really is even though they are identical. So it's a subset, just not a "true" subset.

Answer 5

ooh, that actually explains alot, thanks
