There are 3 even numbers (2, 4, 6) out of 6 possible outcomes on the first roll, so the probability of rolling an even number on the first roll is 3/6 or 1/2.
On the second roll, there are 3 odd numbers (1, 3, 5) out of 6 possible outcomes, so the probability of rolling an odd number on the second roll is also 3/6 or 1/2.
To find the probability of both events happening, you multiply the probabilities together: (1/2) * (1/2) = 1/4.
Therefore, the probability of rolling an even number on the first roll and an odd number on the second roll is 1/4.
