The Power set and subset both are important topics of
the sets in mathematics. Their method of finding is almost the same, but still, there is a major difference between the power set
and subset. Today we will discuss the major difference between the power set and the subset with examples.
Difference between power set and subset:
Sometimes students become when the method of
finding power set and subset, then why
power set and subset are two separate terms? The major difference between the power set and the subset is that subset is
further divided into the proper subset and all possible subsets. While the power
set always contains all possible sets.
4 differences between power set and subset in points:
In this section, we will take in 4 differences between power set and subset
in points
→ Subset is
divided into two parts i.e., proper subset and possible subsets. On the other hand, the power set has all
subsets.
→ There is
another difference between the power set and the subset is that the representation
of both terms is different. The power set is represented by P(S) or P(F) and the
subset is represented by “Subset of A, B
or C”
→ Subset
sometimes includes the given set and sometimes it does not as it depend upon
the condition of the question. While the power set is the opposite of it. It includes
all the proper and improper subsets.
→ Power set
is started and ends with curly brackets ({ }).
Examples of differences
between power set and subset:
We will learn the dissimilarity between the power set and the subset with examples.
Example 1: Find the subset of A={a,e, i}
Solution:
Use this formula: 2n (where “n” is the
number of elements in the above set)
23=8
A={},{a},{e},{i},{a,e},{a,i},{e,i},{a,e,i}
Example 2: Find the proper subset of A={9,10,11}
Solution:
23=8 (The proper subset will be one
less so the proper subset will be 7)
A={},{9},{10},{11},{9,10},{9,11},{10,11}
The last will be excluded as it is an improper subset.
Example 3: Find the all possible subset of A={c,d,f}
Solution:
Again, Use this formula: 2n (where “n”
is the number of elements in the set)
23=8
P(A)= {{},{c},{d},{f},{c,d},{c,f},{d,f},{c,d,f}}
