Discrete Math: Partitions

Recognizing partitions-small finite sets. Define the sets A, B, C, D, and E as follows: .B 2,3,4) Use the definitions for A, B, C, D, and E to answer the questions. Do the sets B and C form a partition of the set D? If not, which condition of a partition is not satisfied? Do the sets B and C form a partition of the set E? If not, which condition of a partition is not satisfied
