The Odd/Even query generates charts that show draw frequencies broken up by the odd/even ratio.
To calculate the odd/even ratio we count how many numbers in a draw are odd, how many are
even, and we divide those two numbers. For example in a draw 5, 8, 13, 19, 34, and 45 the odd/even
ratio is 4/2. For each game listed in the above form there is a definite number of possible draw
results:
