The complement of the event that the number on the first die is even or the number on the second die is even is the event that both numbers on the two dice are odd.
The number of ways that both numbers are odd is 3*3 = 9.
Hence the probability that both numbers are odd is 9/36 or 1/4.
Thus the probability that the number on the first die is even or the number on the second die is even is 1-1%2F4+=+3%2F4.
