The probability of rolling an odd number on one die is 3/6 = 1/2. The probability of rolling an odd number on both dice is (1/2)(1/2) = 1/4. Thus, the probability that at least one die will have an even number is

1 - 1/4 = 3/4.

The probability that the product is even is 3/4.

1 - 1/4 = 3/4.

The probability that the product is even is 3/4.
