Question

difference between subset and proper subset.

Answer 1

Consider two sets A and B, if every elements present in A are also present in B, then the set is aSubset. But, In two sets A and B, B is a proper subset of A, if all the elements of B are in A, but A contains at least one element thatis not in B. For example, if A ={a,b,c} then B={a,c} is a proper subset of A.

Answer 2

Heya!!Here is your answer friend ⤵⤵

➡Subsets - it includes all the elements of the set along with PHI and the set itself . Number of subsets = 2^n where n is the number of elements.

➡Proper Subset = the only difference in subset and proper subset is that proper subset does not include PHi and the set itself .

Let me give an example,

Let set A={2,3,4}

Now

Subsets ={(phi),(2),(3),(4)(2,3),(3,4)(2,4)(2,3,4)}

This was in accordance with the rule 2^n here n=3 so , 2^3=8

Proper subsets = {(2),(3),(4),(2,3)(3,4)(2,4)}

This was leaving the element phi and the set itself .
