B. 1/4
There are 3 even numbers (2, 4, 6) and 3 odd numbers (1, 3, 5) on a six-sided cube. The probability of rolling an even number on the first roll is 3/6 or 1/2. The probability of rolling an odd number on the second roll is 3/6 or 1/2.
Multiplying the probabilities together: 1/2 * 1/2 = 1/4
Therefore, the probability of rolling an even number on the first roll of a six-sided cube and rolling an odd number on the second roll is 1/4.
