Question

State, which of the following pairs of sets are disjoint :

i. {0,1,2,6,8} and {odd numbers less than 10}

Answer 1

Step: Check whether the pair of sets are disjoint

Given: {0,1,2,6,8} & {odd numbers less than 10}

Odd numbers less than 10 are 1,3,5,7,9.
The other set is {0,1,2,6,8}.

$\therefore$ 1 is common in both sets.

And we know that sets having no elements in common are called disjoint sets.

Hence, the given pair of sets are not disjoint sets.
