About Lottery Number Picker Calculator

Numbers are drawn without replacement from a seeded sequence, so the same seed reproduces the same line, and the odds are one over C(pool, pick). Every combination is equally likely, so a seeded pick is no worse and no better than any other line, but it does avoid the clustered numbers people choose by hand.

Formulas

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 8 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
