Class 9th math 3.1 solution english PCTB

Question 3: Write two proper subsets of each of the following sets:

\((ii)\) \(\;\) \( \{0,1\}\)

Solution:

Two Proper Subsets are:

\( (i) \; \) \(\{0\}\)

\( (ii) \; \) \(\{1\}\)


Explanation:

All subsets are \(\phi,\)\(\{0\},\)\(\{1\},\)\(\{0,1\}\)

A proper subset of a set is a subset that is not equal to the original set.

So, we select any combination of elements from the set without including all of them.

The subsets \(\{0\}\) and \(\{1\}\) both contain some (but not all) elements of the original set.
