Question

Sally is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is odd} and let B = {the sum of the number cubes is divisible by 2}. List the outcomes in A ∩ B.

Answer 1

The Answer to the question is { }.

This is because there are no answers that are odd and divisible by 2.

Answer 2

Answer: A∩B is an empty set.

A∩B=
`\phi`

OR

A∩B= { }

Explanation:

Given : A = {the sum of the number cubes is odd}

and B = {the sum of the number cubes is divisible by 2}

We know that odd numbers is not divisible by 2 .

Therefore, the both set have no element common.

Thus, their intersection will be an empty set.

A∩B is an empty set.

A∩B=
`\phi`

OR

A∩B= { }
