2. **Write each set using the roster method and find its cardinality.** a. \( C = \{ x \mid x \text{ is an even number and } 15 \leq x \leq 29 \} \) b. \( X = \{ a \mid a \in \mathbb{Z}, a \text{ is even, and } |a| \leq 6 \} \)

1) Finite Cardinalities A. For any two sets, is this statement true: n(AUB)=n(A)+n(B) - n(ANB) B. For any two sets, is this statement true: n(AUB)=n(A)+n(B)? Explain. C. Is it possible for n(ANB)=0? Explain. D. Is it possible that n(AUB)=0 and n(ANB)=3? Explain. E. Is it possible that n(AUB)=3 and n(ANB)=0? Explain. stions:
