Question

.. Identify the following as a null set or singleton set 1. V = The set of even number lying between 0 and 2 2. W = {0} 3. X = The set of names of the month starting with D.​

Answer 1

Explanation:

Null set : A set in which number of elements is zero or null.

Singleton set : A set in which number of elements is only one.

1) V = { even numbers, lying between 0 and 2 }

Since, no any even number lies between 0 and 2

therefore, V is a null set.

2) W = {0}

There is one element 0 in this set.

therefore, W is a singleton set.

3) X = { Months starting with letter D }

There is one such month December which starts with letter D, therefore,

X is a Singleton set.
