Class 9th math Review Exercise 3 solution english PCTB

Question 2: Write each of the following sets in tabular forms:

\((v)\) \(\;\) \(\{x|x \in O \wedge 5\le x<7\} \)

Solution:

Tabular Form:

\(\{\}\)\(\;\)Or\(\;\) \(\phi\)


Explanation:

\(\{x|x \in O \wedge 5<x<7\} \) means that, we are looking for odd numbers that lie between \(5\) and \(7\).

But the only number between \(5\) and \(7\) is \(6\), and since \(6\) is not odd, there is no odd number between \(4\) and \(6\).

So, the set is empty.
