Question

If A is subset of B and B is subset of C then Prove
Аis subset of С​

Answer 1

Answer:

Let A is a subset of B and B is a subset of C.

Then there is an x in B such that, for every x in B,x is in C and there exists an x in A such that, for every x in A,x is in B. Thus, for every x in A,x is also in C, and thus A is a subset of C.

Hence proved.

Let A is a subset of B and B is a subset of C.

Then there is an x in B such that, for every x in B,x is in C and there exists an x in A such that, for every x in A,x is in B. Thus, for every x in A,x is also in C, and thus A is a subset of C.

Hence proved.
