Question

If A subset B , then find A union B , A intersection B , A-B , and A-(A-B) interms of A and B​

Answer 1

b) if the intersection gives u set A, it means A is a subset (fully lies within) of B. Hence, A ⊂ B. c) if the set difference gives you A, it means that A and B do not share any elements, i.e. they are mutually exclusive.
