In theory, one-third 33.3% of the 13,983,816 possible combinations in a 49-ball Lottery are 3 high and 3 low. In practice, in over 300 lottery draws, look at the table below and you will see the results that emerged.
Three of the combinations account for 81.1% of all possible combinations. Whether we are talking Odds and Evens or Highs and Lows, clearly around 80% of the winners are either 3-3,2-4 or 4-2. Keep around 50% of the numbers in each set high and 50% low.
You can take this concept further if you wish. For the Lottery you should select roughly 1/3 of the numbers in the 1-16, 17-32, 33-49 segments.
