Question

2. what does it mean for two sets a and b to satisfy a ∩ b = ∅? (a) a = ∅ (b) b = ∅ (c) this means the two sets have no elements in common; they are disjoint. (d) a ⊆ b. (e) b ⊆ a

Answer 1

For two sets A and B to satisfy A ∩ B = ∅, it means that the two sets have no elements in common; they are disjoint.

Step-by-step explanation:

For two sets A and B to satisfy A ∩ B = ∅, it means that the two sets have no elements in common; they are disjoint. This means that there is no intersection between set A and set B. In other words, there are no elements that are present in both sets A and B.
