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	12	2.86%	2.53%
1 odd / 4 even	56	13.33%	14.54%
2 odd / 3 even	120	28.57%	31.65%
3 odd / 2 even	155	36.90%	32.55%
4 odd / 1 even	68	16.19%	15.82%
5 odd / 0 even	9	2.14%	2.91%

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