Are the odds better picking the same numbers every draw?
(1/N) to the Y p0wer wher e N = numbers in the pool and Y =
number of draws.
For example if there are 10 numbers and you draw four times
probability is 1/10 x 1/10 x 1/10 x 1/10 = 1/10000
Edit:
Not sure what all that is about since it seems to have nothing
to do with the question.
If the draws are fair and if each draw is independent then
whether you pick the same numbers every time or change them every
time makes no difference whatsoever. Each set of numbers will have
the same probability of winning as every other set, and that
applies from one draw to the next.
