Explanation:
3/6 = 1/2 of the numbers on the cube are even (2,4,6)
If we wanted both cubes to show an even number, then this comes up (1/2)*(1/2) = 1/4 of the time.
There are 6*6 = 36 outcomes total, so there are (1/4)*36 = 9 outcomes when both dice show an even number.
---------
Those nine outcomes are listed below
You probably have noticed that A has 3 choices (2,4,6) and so does B. That gives 3*3 = 9 outcomes total. This is an alternative pathway compared to the previous section.
