Question
Text from your selection A ⊂ B (ii) A – B = Φ
Solution
You didn't provide a question to answer. However, I can explain the given mathematical statements:
(i) A ⊂ B: This is a notation in set theory. It means that A is a subset of B. Every element in set A is also in set B.
(ii) A – B = Φ: This means that the difference of set A and set B is an empty set (Φ). In other words, there are no elements in set A that are not in set B. This is another way of saying that A is a subset of B.
