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	25	2.88%	2.57%
1 odd / 4 even	139	16.00%	15.01%
2 odd / 3 even	280	32.22%	32.42%
3 odd / 2 even	295	33.95%	32.42%
4 odd / 1 even	117	13.46%	15.01%
5 odd / 0 even	13	1.50%	2.57%

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(56, 5). A common pattern does not make a specific ticket more likely to win.
