### Lotto Tip #2: Any 5 Of The Jackpot Numbers Are Rarely Repeated Together

Take 5 numbers from any previous jackpot numbers and combine them with a new number? Will they win, say 6 matches? Possible but very unlikely.

A group of 6 numbers can form six 5-number combinations. For example, from the March 8, 1995 draw, the jackpot numbers 4-20-22-30-34-38 can form the following 5-number combinations:
• 04 - 20 - 22 - 30 - 34
• 04 - 20 - 22 - 30 - 38
• 04 - 20 - 22 - 34 - 38
• 04 - 20 - 30 - 34 - 38
• 04 - 22 - 30 - 34 - 38
• 20 - 22 - 30 - 34 - 38
If you tried these numbers again, they have never won up to this time. The reason is that, any 5 numbers from previous jackpot numbers rarely win again.

5805 jackpot numbers from lotto 6/42, 6/45, 6/49, and 6/55 studied. From 5805 jackpot draw results, 34830 five-number combinations are formed. Out of 34830 combinations, only 395 combinations won twice or repeated. None of them won more than twice.

Therefore, for every 87 combos, one occurs twice; or a ratio 1:87 or 1.15% probability of winning again calculated as follows:
```
87.177 = (34830 - 395) ÷ 395
1.15% =  1 ÷ 87.177
1.15% =  395 ÷ (34830 - 395)```

As of 8/27/2008, 3,889 combined results have been drawn from the 6/42, 6/45, and 6/49 lotto. These results produce 23,334 quints. I wanted to find out if there's any quint that would be most often 'hot'. I found out that out of 23,334 quints, only 192 quints appeared twice; and not one appeared more than twice. Therefore, the probability of a quint being drawn twice is only 0.82%.

That means, if 5 of your lotto numbers have been part of any drawn result before, it is unlikely that they'd be drawn again. So, might as well substitute one number with another one to form a new combination.
