Thread: Sets

Apologise if in the wrong forum. But it's just a quick check of my work needed please.

E = {1,2,3,4,5,6,7,8}
P = {2,3,5,7}

1) List the members of P'?

Is P' in affect all the P is not? So P' = {1, 4, 6, 8}

2) The set Q satisfies both the conditions Q proper subset of P and n(Q) = 3. List the members of one set Q which satisfies both these conditions?

Would one be... {2, 3, 5} or (3, 5, 7} or {2, 5, 7} etc...

If P' means the complement of P in E, then both are correct if you list one more in #2.
