As shown in Table S71, 28.5% of the 7 number combinations consist of 4 even and 3 odd balls, and 29.9% consist of 3 even and 4 odd balls. These two total to 58.4% of the combinations. Then, 31.9% contain either 5 even and 2 odd, or 2 even and 5 odd balls. These four compositions account for 90.3% of all combinations. The rarest numerical combinations are those where the white balls are all even or all odd. In both of these cases, there is only a 1.0% chance of either one occuring. So starting off, try to avoid combinations containing all odd or all even numbers. This may increase your chances of having a winning combination.
Note that the table is not symetrical. There are more combinations containing Odd numbers than Even numbers. The reason for this is that the white ball pool is numbered 1 to 47. In this, there is 1 more odd number than even, thus accounting for the difference in probabilities.
