## Observations

- No
**6**winning numbers came from one group alone. Therefore, 10•12•13•14•15•16 or 20•22•23•24•25•26 or something similar is very unlikely to happen. The probability is 0%. - Likewise, no
**5**winning numbers came from one group alone. - Though there were a few cases when
**4**winning numbers came from one group alone, the probability is very low, ranging from 0% to 0.9%. If such occurred, it was an extraordinary case. For example, the result of 5 Aug 2016 02 • 06 • 08 • 09 • 30 • 52 is a very extraordinary case, 4 numbers coming from the single unit group. **Three**winning numbers coming from one group alone is also rare. The probability ranges from 3.4% to 6.5%. These are exceptional cases. The result of 3 Dec 2017 14 • 15 • 23 • 40 • 43 • 47 is an example of a rare case wherein 3 numbers came from the group of 40s.- The probability of
**2**winning numbers coming from one group alone ranges from 17.8% to 25.2%. Collectively, however, this case has occurred 265 times out of 325 results, a probability of 81.5%. It means that it is safe to play 2 numbers coming from one group. - The strongest probability is that
**1**number from each group can almost definitely win. This case has occurred 313 times out of 325 results, a strong probability of 96.3% with plus or minus 2.7% margin of error at 99% confidence level. This means that this statement is 93.6% to 99% closer to truth. - However, it is also possible that a particular group would not produce a winning number. Almost all results, 319 all in all out of 325, recorded such case. In fact, it is more probable that a group would produce no winning number than to produce 2 winning numbers. It is but logical that if a group produced 2 winning numbers, one group would produce none. This statement has a probability of 98.15% with a 1.93% margin of error.
