If A = {a, b, c} then the number of possible subsets isA.3B.8C.6D.None of these

If A is a subset of B and B is a subset of C, then cardinality of A ∪ B ∪ C is equal to

If A ⊂ B and B ⊂ C, what can we conclude?a.A = Cb.C ⊂ Ac.B = Cd.A ⊂ C

Let A, B, and C be sets.Then, in general, A - (B INTERSECTION C) = (A - B) INTERSECTION (A - C).Question 5AnswerTrue False
