Stephanie 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 3}. list the outcomes in a ∩ b.
{1,3,5,7,9,11}
{1,3,9}
{3,9}
{3,9,12}

The outcomes of rolling two cubes are shown in the table below (the outcomes is added up). The members of A are circled while the members of B are boxed. The members of A that also members of B is both circled and boxed.

P(A) = {3, 5, 7, 9, 11}
P(B) = {3, 6, 9, 12}
P(A∩B) = {3,9}

The answer that i got was 8/3
