Consider the sample space S = {copper, sodium, nitrogen, potassium, uranium, oxygen, zinc} and the events A = {copper, sodium, zinc}, B = {sodium, nitrogen, potassium}, C = {oxygen}.

List the elements of the sets corresponding to the following events:

(a) A

;

(b) A ∪ C;

(c) (A ∩ B

) ∪ C

;

(d) B ∩ C

;

(e) A ∩ B ∩ C;

(f) (A ∪ B

) ∩ (A ∩ C).
