Question

Find the number of subset of A if n(a)=4

Answer 1

Given : n(A) = 4

To Find : number of subset of A

Solution:

if number of elements in  a set are n

Then number of subsets of A = 2ⁿ

n(A) = 4

=> numbers of elements in set A = 4

Hence number of subsets = 2⁴ = 16

number of subset of A if n(A)=4  is 16
