Duplicates, Ranges, And Luck

How it works

Two settings decide almost everything about a draw.

01

No duplicates = a lottery

Each number is removed once drawn, so six from 1–45 behaves like a lottery ticket.

1–45, pick 6 = 8,145,060 combos

02

Duplicates = dice

Every draw goes back into the pot, so each pick is independent. Two sixes in a row is not a bug.

Each pick = 1/6, always

03

The range sets the odds

Odds for any one number are simply one over the size of the range, inclusive of both ends.

1–45 → 2.22% each

04

You cannot ask for more than exist

With duplicates off, asking for more numbers than the range holds is impossible — widen the range instead.

Questions

03
01

Can I use negative numbers?

Yes. Any two integers work, and the smaller one is treated as the floor.

02

How random is it?

It uses the browser Math.random generator. Good enough for lotteries and games, not for cryptography.

03

Are the numbers sorted?

They are shown in the order they were drawn, with a sorted line underneath.
