It is not as easy as you describe it.

You, and I, and anybody else, can not define

what is important to consider that will constitute the basis of an intersection of such subsets.

If we consider many such subsets then that intersection may have more than one number.

A Lotto game is "binomial" or having two terms.

As you know by now, some numbers have come more than the expected frequency which means that others have come as many times less than the expected.

As of to what will come up next, that is always a combination of those frequent & less frequent numbers.

So you (we), have to assume that some group of numbers may have the winning numbers of the next draw.

So what you should do is, describe which groups you consider important based on past observations

of the last few draws.

Can you describe which these groups are?
