Given:

The set is:


R=\{a,b,c\}

To find:

The number of subsets in set R.

Solution:

Formula for number of subsets in a set of
n elements is

Number of subsets =
2^n ...(i)

We have,


R=\{a,b,c\}

Here, the number of elements are 3. Putting
n=3 in (i), we get

Number of subsets =
2^3

=
8

Therefore, the number of subsets is 8 and the subsets are
\phi,\{a\},\{b\},\{c\},\{a,b\},\{a,c\},\{b,c\} and
\{a, b, c\}.
