Which of the following sets does not have a proper subset?
{x:xQ}
{x:xN,3<x<4}
{x:xQ,3<x<4}
{x:xN}
As we learnt
Proper Subset -
Let A and b be two sets if A B and A
B. Then A is a proper subset of B
-
Since this set is an empty set.It has no proper subset
Option 1)
{x:xQ}
Option 2)
{x:xN,3<x<4}
Option 3)
{x:xQ,3<x<4}
Option 4)
{x:xN}
