Assume a weekly lottery that draws six numbers from the series 1 through 40,
with no duplicates. Statistically speaking, am I better off repeatedly playing
the same six numbers selecting six numbers at random each week?
It seems to me that if (in a different example) you randomly pick a number
between 1 and 10 and I have to guess it, my chances of getting it right are one

time (assuming that you likewise randomly re-select your number each time). Is
this correct?
And does it also apply to a 40-digit lottery pool?
I’m always embarrassed that I don’t know this stuff, but I never had a course in
statistics, and I tend to second-guess my reasoning.
Thanks for your input.
Dave!
