Question

find the number of proper subsets of a set A=a,e,i,o,u​

Answer 1

Answer:

25

Step-by-step explanation:

the no. of proper subsets = n^2

(n=5 ) so, no. of subsets =5^2=>25

Answer 2

Answer:

There are 31 proper subsets of set A.

Step-by-step explanation:

Proper subsets:-

• A set that contains a few elements of the original set is called the proper subset.
• The only set which is improper is the set itself.
• The number of proper subsets of a set is $2^n-1$, where $n$ = no. of elements present in the set.

Step 1 of 1

Consider the given set A as follows:

Set A = {$a,e,i,o,u$}

Observe that there are 5 elements in set A, i.e.,

$n=5$

Then,

The number of $proper$ subsets of set A is,

= $2^n-1$

Substituting the value n = 5, we get

= $2^5-1$

= 32 - 1

= 31

Final answer: There are 31 proper subsets of set A.
