Subset and proper subset

Distinguish : Subset and proper subset

If A = {a, b, c} then name all subsets and all proper subsets of A.

Determine whether the statement is true or false. If it is true, prove it. If ir false, give an example. If A subset B and B subset C, then A subset C

Find the number of subsets and number of proper subsets of a set X={a,b,c,x,y,z} .

The set does not have proper subset is

If a set A has 4 elements , then the total number of proper subsets of set A is :

If a set has 2 elements , then how many proper subsets are there for the given set?

if A is a proper subset of B and B is a proper subset of C then would A be a proper subset C

if A is a proper subset of B and B is a proper subset of C then would A be a proper subset of C?
