What matters
Every combination is equally likely, so the numbers you pick do not change your chance of winning. They only change how many people you would share the prize with.

Every combination is equally unlikely

Draws random lottery lines and shows the true odds of matching every number in the combination.

There is no clever set of numbers. A draw of six from forty-five has 8,145,060 combinations, all with exactly the same chance, and 1-2-3-4-5-6 is as likely as anything that looks more random.

The one thing your choice does affect is what happens if you win. Dates cluster below 32, patterns on the ticket grid are popular, and a winning line that thousands of people also picked is a prize split thousands of ways.

How to use

Set how many numbers are drawn and from what range.
Say how many sets to generate.
Look at the number of combinations: that is the real chance of matching them all.
The sum and the odd-even split are reference lines only; they have no bearing on the odds.

How many combinations each format holds

Each row is a run of this calculator for one of the common formats. The combination count is a binomial coefficient: how many ways k numbers can be chosen from n without regard to order.

The format decides everything. Four extra numbers in the range — from 45 to 49 — nearly doubles the combinations, from 8.1 to 14 million. And one extra number drawn costs more: 5 from 50 gives 2.1 million, while 6 from 49 gives almost seven times that.

What this calculator shows

One or several lines drawn from the seed
The exact number of combinations and the odds of matching all
The sum and the odd–even split of the first line

What to keep in mind

The draw is without replacement: each number appears once in a line.
The odds are for matching every number. Smaller prizes for partial matches are far more likely and are not shown here.

FAQs

Do the numbers I pick change my chances?

No. Every combination is equally likely. They only change how many people you would share a jackpot with.

Are there cold and hot numbers?

No. Balls have no memory either, and a number that has not appeared for a year is exactly as likely as any other on the next draw.

Why avoid dates?

Because they only cover 1 to 31, and enormous numbers of people play them. A winning line made of dates is usually shared several ways.

How many combinations are there in 6 from 45?

8,145,060. In 6 from 49 it is 13,983,816, which is why the extra four balls matter so much.

Do “lucky” numbers improve the odds?

No. Every combination is equally likely, and 1-2-3-4-5-6 comes up exactly as often as any other. The only difference is how many other people picked the same set and would share the prize.

Then why show the sum and the odd-even split?

As descriptive features of the set, nothing more. They have no effect on the probability: the calculator shows them because many players look at the balance of odd and even, not because it matters to winning.

Worked example

Six from forty-five

Input: seed "unitools", 6 numbers from 45, 2 lines

Output: 8 — 19 — 23 — 36 — 40 — 41

Note: The odds are 1 in 8,145,060. Two different lines make it 2 in 8,145,060, or 1 in 4,072,530.
