Question

Let Bi = {x ? ? | 0 ? x ? i} for each integer i = 1, 2, 3, 4. (a) Find B1 ? B2 ? B3 ? B4. (Enter your answer in set-roster notation.) (b) Find B1 ? B2 ? B3 ? B4. (Enter your answer in set-roster notation.) (c) Are B1, B2, B3, and B4 mutually disjoint? Explain. Yes, because the intersection of the sets B1, B2, B3, B4 is empty. Yes, because the union of the sets B1, B2, B3, B4 is empty. Yes, because no two of the sets B1, B2, B3, B4 have any elements in common. No, because the sets B1, B2, B3, B4 are disjoint. No, because no two of the sets B1, B2, B3, B4 are disjoint.

Step 1

B1 = {x ∈ ℤ | x < 1} = {} B2 = {x ∈ ℤ | x < 2} = {1} B3 = {x ∈ ℤ | x < 3} = {1, 2} B4 = {x ∈ ℤ | x < 4} = {1, 2, 3} Therefore, B1 ∪ B2 ∪ B3 ∪ B4 = {1, 2, 3} Show more…
