Unless you think the selection process is biased, each number has an equal chance of being picked. Numbers do not remember whether they were picked recently. You don't need to do any "analysis"; pick your favorite number and know you have the same chance as the next guy.

The formula for combinations works well for calculating lottery odds of winning.

n things taken r at a time. If there are 100 numbers to pick from, n = 100. If there 8 numbers in the winning set, then r = 8.

n!/(r!(n-r)!) = number of possible sets

Your chances of winning are

1/(n!/(r!(n-r)!))

For n = 100, r = 8

possible combinations of 8 numbers are
100!/(92!8!) = 1.86 x 10^(11)

The odds for winning

1/(1.86 x 10^(11)) = 5.37 x 10^(-12)

Makes me wonder why I buy lottery tickets!
