We have to assume that the intention is that S represents the set of possible outcomes.
A. TRUE — any of the faces may appear
B. false — 0 is not a possible outcome and is not in set S.
C. TRUE — {5, 6} is a subset of S
D. TRUE — A = S \{5}
E. false — even numbers are {2, 4, 6}. The complement of that includes 5, which A does not.
