Question

10. Let A, B and C be three sets. If Ac B and B E C, is it true that AEC ? If not give an
example.
​

Answer 1

Answer:

No.

If A = {1,2} and B = {1,2,3}, A is clearly a subset of B.

We observe that C is a set of sets since the set B belongs to set C

If a set B = {1,2,3} belongs to the set C, it is not necessary that the set A = {1,2} should belong to C.

However, if A=B (since the set A can be equal to set B) then A belongs to C.
