Latest Update June 2009

As our sample data grow, probability rates may vary. So, I'm giving you updates if our early probability findings have changed. So, far nothing has changed significantly.

Probability of a lotto result being drawn twice is 1/4187 or 0.02%. Based on this, if your 6 lotto numbers have been drawn before, it is unlikely that is going to be drawn again.

Probability of a quint being drawn again is 217/25122 or 0.86%. A quint is a 5-number combination formed from 6-number combination. Out of 6 lotto numbers, you can form 6 sets of quints.Based on the probability rate, if 5 of your numbers have been part of any drawn result before, it is unlikely that your set of 5 numbers is going to be drawn again. A repeat is possible but the chances are very, very low.

Probability of quad being drawn more than twice is 1244/62805 or 1.98%. A quad is 4-number combination formed from a 6-number combination. Out of 6 lotto numbers, you can form 15 sets of quads. In the case of quads, the chance of being drawn again for the third time is unlikely.

Coming up next - frequency distribution. We'll see if there are significant trends if we group the numbers like 1-9, 10-19, etc.
