1. ## 1 out 101

Hi, I am hoping that someone can help me out with this?

If I have 54 numbers on a roulette table, and there is a random generator picking the numbers, on average in 54 picks every number should in theory come out once. What if I had 6 of the 54 numbers, in theory my numbers should be picked 6 times out of 54.

My situation is I had exactly 101 spins of this roulette table, I covered 6 of the 54 numbers, but it only dropped in 1 of my 6 numbers once, it should have dropped in nearly 12 times, what is the odds or probability of this happening?

Really appreciate the help if any one can assist.

Assuming each spin is fair, then it is easy to see the probability that your number come out is

Assuming each spin is independent to each other. Now the number of times dropped in 101 spins follows .

And the probability that it dropped exactly 1 time is

Thank you for your reply, so I take it that for this to happen then I would have to do this 101 times in theory for this to happen once?
