Recognizing partitions - small finite sets. Define the sets A, B, C, D, and E as follows: A = {1, 2, 6} B = {2, 3, 4} C = {5} D = {x ∈ Z: 1 ≤ x ≤ 6} E = {x ∈ Z: 1 < x < 6} Use the definitions for A, B, C, D, and E to answer the questions. (a)Do the sets A, B, and C form a partition of the set D? If not, which condition of a partition is not satisfied? (b)Do the sets B and C form a partition of the set D? If not, which condition of a partition is not satisfied? (c)Do the sets B and C form a partition of the set E? If not, which condition of a partition is not satisfied?

2.7.1: Recognizing partitions - small finite sets.

Define the sets A, B, C, D, and E as follows:

  • A = {1, 2, 6}
  • B = {2, 3, 4}
  • C = {5}
  • D = {x ∈ Z: 1 ≤ x ≤ 6}
  • E = {x ∈ Z: 1 < x < 6}

Use the definitions for A, B, C, D, and E to answer the questions.

(a)Do the sets A, B, and C form a partition of the set D? If not, which condition of a partition is not satisfied?
(b)Do the sets B and C form a partition of the set D? If not, which condition of a partition is not satisfied?
(c)Do the sets B and C form a partition of the set E? If not, which condition of a partition is not satisfied?
