Which of the following pairs of sets are disjoint
$\{1,2,3,4\}$ and $\{ x:x$ is a natural number and $4\, \le \,x\, \le \,6\} $
Which of the following pairs of sets are disjoint
$\{1,2,3,4\}$ and $\{ x:x$ is a natural number and $4\, \le \,x\, \le \,6\} $
$\{1,2,3,4\}$
$\{ x:x$ is a natural number and $4\, \le \,x\, \le \,6\} = \{ 4,5,6\} $
Now, $\{1,2,3,4\} \cap\{4,5,6\}=\{4\}$
Therefore, this pair of sets is not disjoint.
