(a) Given statement: A square is a quadrilateral and its four sides are equal

The component statements are:

P: A square is a quadrilateral

Q: A square has all its sides equal.

In this statement, the connecting word is “and”

We know that a square is a quadrilateral

So, the statement P is true.

Also, it is known that all the four sides of a square are equal.

Hence, the statement “Q” is also true.

Therefore, both the component statements are true.

(b) Given statement: All prime numbers are either even or odd

The component statements are:

P: All the prime numbers are odd numbers

Q: All the prime numbers are even numbers

In this statement, the connecting word is “or”

We know that all the prime numbers are not odd numbers

So, the statement P is false.

Also, it is known that all the prime numbers are not even numbers.

Hence, the statement “Q” is also false.

Therefore, both the component statements are not true
