Jeremy is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is even} and let B = {the sum of the number cubes is divisible by 3}. List the outcomes in A ∩ B.
@amistre64
write out your sets in roster form ... in other words, list their elements
{6, 12} {3, 6, 9, 12} {2, 4, 6, 8, 10, 12} {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
may help to write a universal set
we can rule out 2 sets, can you tell me why?
?
actually 3 can be rules out ...
youll have to explain your confusion better than that, i simply cant read minds that well
i dont know what ^ means like the U but downwards
from the information that is stated in the problem, what part or parts of it do you now understand? ok, lets call it an "n" which is a good representation of it. "n" means AND it is asking for what elements are the same in each defined set
the solution will contain values that are even; and divisible by 3 .. nothing else
ok
so which option has only even numbers, which are divisible by 3?
(3,6,9,12)?
no, but a good guess. 3 and 9 are not even numbers. 6 and 12 are
oh yea so its 6 and 12 thats it
yep, 6,12 would be my pick
can u help me in my last question?
not at the moment ... but good luck
alright
