Based on 338 Grand Lotto 6/55 results, only 42 foursomes won twice. That's a low probability rate of 0.84%. None won more than twice.
The 338 jackpot numbers form 5070 foursomes. Out of this number, 5028 are unique; 42 of these unique numbers won twice. The probability rate of 0.84% is calculated as follows: 0.84% = 42 ÷ 5028
On another angle, if 42 foursomes occurred twice, it means 84 foursomes are duplicates. These 84 foursomes come from 70 draw results. That means that for every 5 [338 ÷ 70 = 4.83] draws, one of them produced 4 winning numbers equivalent to the same 4 numbers drawn from one of the other 333 jackpot numbers. So, the probability of correctly guessing which previous draw result would make a match is 0.3% [1 ÷ 333 = 0.003] .
ApplicationTo eliminate the lower probability brings you closer to a match. If your lotto combination comprise a winning foursome, might as well change one number to break the winning foursome. This technique makes it easier for you to decide which numbers should you combine because it narrows down your choices. On the other hand, if your objective is to earn multiple smaller winnings rather than the jackpot, the winning foursomes can give you an idea as to which numbers stick together. Stick to the trick though to drop one number from the foursome and mix the remaining 3 with other numbers.
