Question

If, $A=\left\{\text{all even natural numbers}\right\}$ and $B=\left\{\text{all odd natural number}\right\}$ then, a and b are which type of sets ?

Answer 1

Given,

$A=$ all even natural numbers
$B=$all odd natural numbers

There is no common number between even and odd numbers

So Both $A,B$ are disjoint sets
