probability

[hello]

Imagine a lottery with only thirty balls (1-30).

The probability of getting 4 or more balls correct is 5/609.

What is the best 609 tickets to pick?

By best I mean the most effiecient, the tickets that cover the most possibilites of number combinations to give the best chance of getting four or more numbers.

If you don't have the time to make a list (it is a lot of numbers) then maybe you know of a way to make something like excel generate the list I am after. If you do then can you tell me how.

Thank you.

You simply choose 609 tickets all with different combinations of numbers. If the lottery is not crooked all numbers have an equal probability of being chosen. No number is more likely to be picked than another.

Each number is equally probable to hit in a lottery that's completely honest, but, if you must gamble, you better choose what you think might be unpopular numbers.

Correct. Which means avoiding things like consecutive numbers, numbers that correspond to dates (though lots of them do), etc.
