Paul 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 4}. List the outcomes in A ∪ B.

Maddie2005:

ok so A would be odd numbers

Maddie2005:

like

Maddie2005:

1,3, and 5

Maddie2005:

and then divide every number 1-6 by 4

ponylover56:

what

Ruthy:

{1,2,3,4,5}this is d union of a and b becoz after listing out d set A and set B then u join it together

Next time provide the choices. This question has been asked before (https://questioncove.com/updates/5410a1fbe4b0670f10110e1e), the part that I think you'd need is⬇ The numbers in each cube go from 1 to 6. When the numbers are added, the lowest sum will be 2 and the highest sum will be 12. \[Sum\ = {2,\ 3,\ 4,\ 5,\ 6,\ 7,\ 8,\ 9,\ 10,\ 11,\ 12}\]\[A = {3,\ 5,\ 7,\ 9,\ 11}\] \[Sum\ of\ number\ cubes\ divisible\ by\ 4\ are:\ 4,\ 8,\ 12\] \[So\ B = {4,\ 8,\ 12}\] \[A\ =\ {3,\ 5,\ 7,\ 9,\ 11}\]\[B\ =\ {4,\ 8,\ 12}\]\[A\ union\ B = {3,\ 4,\ 5,\ 7,\ 8,\ 9,\ 11,\ 12}\] This is all from the link above.
