Probability Distribution of delay of N numbers

[roufor69]

Hi everyone!

I'm looking for a formula (if any) to define the Probability Distribution of the delay of N numbers (European Roulette).

So the variables will be N: amount of numbers, S: number of spins, P: Probability (%)
e.g. what are the odds of 10 numbers not appearing for 1,2,3...30,31... spins?

Thank you in advance

i'd say depends on how you get the 10 numbers. If when you arrive at the game, the 37#'s euro wheel are all due,so as the #'s get hit, eventually you'd be down to 10 left, NOW seen 10 numbers this way, take 21 spins. If a random 10 #'s dont know but i've seen 8 random take 36 spins

Thanks for the reply!

I need a formula to calculate the probability that a set of N specific (same for every spin) numbers (no matter if hit or not) will not hit for each spin from a sequence of S consecutive spins

eg for 10 specific numbers, what is the probability that none of them will hit in next spin (spin 1), spin2...spin 50 and so on.
or vice versa: that will hit

so that I can make a table like this:

Spin    Probability
   1           25%
   2           15%
  ...           ...
  50          0,07%

Thanks
