Given:
The set is:
To find:
The number of subsets in set R.
Solution:
Formula for number of subsets in a set of elements is
Number of subsets = ...(i)
We have,
Here, the number of elements are 3. Putting in (i), we get
Number of subsets =
=
Therefore, the number of subsets is 8 and the subsets are and .
