Understanding the Bounds
How to use the above data? In Lotto 642, it suggests that your 6-number combination should be between the lower limits and the upper limits. For example, don't bet yet on 1-2-3-4-5-6 because statistics says that your numbers should be greater than 1-2-3-4-8-10. You can try, however, 1-2-3-5-9-11, for example. On the other hand, your numbers should not be greater than 26-33-38-40-41-42. That means, waging on 27-34-40-41-42 is not advisable. Same rule applies for Mega645 and Super649.

To narrow down your choices of combinations, you may opt to increase or decrease the lower and upper limits in such a way you consider only the 90% with high probability.
