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	15	2.44%	2.48%
1 odd / 4 even	88	14.33%	14.44%
2 odd / 3 even	187	30.46%	31.68%
3 odd / 2 even	199	32.41%	32.67%
4 odd / 1 even	109	17.75%	15.84%
5 odd / 0 even	16	2.61%	2.89%

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