B. 1/2
There are 3 odd numbers out of 6 on a six-sided cube, so the probability of rolling an odd number on the first roll is 3/6 = 1/2.
On the second roll, the remaining numbers are even, so the probability of rolling an even number on the second roll is also 1/2.
Therefore, the probability of both events occurring is (1/2) * (1/2) = 1/4.
