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

{ }

Explanation:

I took the test :)

Answer 2

To be odd means that the number is not divisible by 2, so set A is the opposite of set B. The two sets have nothing in common. If a number is odd, then its not even, and vice versa. The intersection of set A and set B is the empty set.

Answer: Empty set

Note: To write the empty set, we could use curly braces with nothing inside them like this { } or we can use the symbol
`\varnothing`
