Question

Is A = {x: x<1 and x > 3) an empty set? Give reasons​

Answer 1

Step-by-step explanation:

yes A is an empty set....Because according to condition x is greater than 3 and less than 1 which is not possible.

Answer 2

Step-by-step explanation:

Here, A is a set of those elements which are less than 1 but greater than 3.

How is this possible? we can't think of any number which is less than 1 & greater than 3 at the same time.

obviously it will be an empty set.
