These statistics describe past drawings; they do not predict outcomes. A number is never “due.” Every valid combination under these rules has the same chance in an independent, fair drawing. Methods & limitations →

Odd and even white-ball splits
Pattern	Drawings	Observed share	Theoretical share
0 odd / 5 even	8	3.92%	2.37%
1 odd / 4 even	29	14.22%	14.23%
2 odd / 3 even	64	31.37%	31.75%
3 odd / 2 even	62	30.39%	32.93%
4 odd / 1 even	35	17.16%	15.87%
5 odd / 0 even	6	2.94%	2.85%

Why aren't all splits equally likely?

Each combination is equally likely, but some patterns contain more combinations. The theoretical share for k odd balls is C(odd pool, k) × C(even pool, 5 − k) / C(59, 5). A common pattern does not make a specific ticket more likely to win.
