Because 3/6 of the sides on a number cube have even numbers, the probability of rolling even on one number cube is 1/2(equivalent of 3/6). But since you're rolling twice, you multiply the probability of one by itself (therefore rolling 2 number cubes). So:

1/2x1/2=1/4

The probability of rolling an even number when a number cube is rolled twice is 1/4, 25%, or 1 out of 4.
