Question

if A B and C are sets then show that A subset B => C-B subset of C-A​

Answer 1

Answer:

Hence proved that  is the subset of  if A is a subset of B.

Step-by-Step explanation:

Let us consider the sets of A, B and C as follows

A = {a, b, c}

B = {a, b, c, d, e}

C = {a, b, c, d, e, f, g}

So here, we are taking A as the subset of B and B is the subset of C.

∴  = {f,g}

∴  = {d,e,f,g}

Here, we can find that the  contains the values of  and  has more values other than  

Hence we can prove that  is the subset of  if A is the subset of B.
