Does the order of the numbers matter? For example, is the sequence 24-32-56 treated in a different way than 32-56-23?
Apart from that ambiguity, this is a simple combinatorics problem.
The order of the numbers isn't a problem. It can be in any order.
I don't know anything or nearly nothing in combinatorics problem for PowerBall or any other lottery.
We imagine I want to play with 3 white numbers that are even and 2 white who are odd or 3 white numbers that are odd and 2 white even.
Also, I want to choose three numbers between 1 and 34 and two between 35 and 69 or three number between 35 and 69 and two between 1 and 34.
How calculate how many combinations I can play with 3 even and 2 odd (I have the same question for the reverse) and three between 1 and 34 then two between 35 and 69 (I have the same question for the reverse) ?
I don't know how to calculate the numbers of combinations with the limitations of my choice.
The limitations of my choice are those previously said in this message.
